The Hygienic Centrifugal Pump For Absolute Process Reliability


In addition to disconnecting and shutting off, one other thing is of the utmost importance in a line: it must convey your products with reliability. As of now Everest Industries therefore also offers innovative centrifugal pumps in addition to the high-quality valves. The development of these new components took account of all requirements to be met in terms of top-quality products, hygiene and energy costs.
The expanded Everest Industries modular component system now enables us to offer the standard for conveying, shutting off and mix proof shutting off from a single source. For you this means you benefit from the extensive experience of our team – because we know the requirements to be met by components in the beverage and food industry down to the last detail.
With modern methods and the latest materials, we contribute to improvements in performance at more and more points on the production line – with the optimised design of your lines and with maximum process reliability.
The optimised design of your line with Everest Industries products guarantees absolute process reliability. With each component precisely coordinated with the rest, smooth production processes are made far easier.
Our focused development work is based on the requirements of production operation. Thanks to our decades of experience in the construction of lines, we have been able to ensure that Everest Industries offers distinct advantages:
– Product selection on a modular basis
– New connections to motors
– New, safe seal concept designed for high process requirements and offering optimised service lives
– Low costs as a result of reduced energy consumption with high-efficiency motors and optimised design
Every detail of the design was included to ensure outstanding performance during day-to-day operation. The seal materials are in accordance with the latest technology and the enclosures are of optimised design, with FEM support, to guarantee maximum service lives.
The seals in the product chamber can be replaced quickly and easily in Everest Industries centrifugal pumps. The gap dimensions can be adjusted easily without the need for special parts.
The products are produced in-house using tested materials, and acceptance test reports are generated. All components comply with regulatory requirements. Lot tracking using data matrix codes and serial numbers ensures that functionally relevant parts can be unequivocally identified throughout the entire life cycle of the product, right back to the melted material.
The main requirement to be met by a pump is that it conveys the product to optimum effect. The new Everest Industries series of pumps does this smoothly and gently thanks to precisely designed flow paths that are free of dead spaces. This keeps production stoppages to a minimum and reduces the time and personnel costs required for maintenance and cleaning. A low NPSH value and IE3 high-efficiency motors provide outstanding power for low energy consumption. With precisely calculated housings and impellers and seals designed on the basis of the finite element method (FEM), optimum efficiency and therefore energy saving is guaranteed.

Everest Industries offering Sanitary Centrifugal Pumps


Designed for use in the Bio-Pharmaceutical industry, the Everest Industries high purity, sanitary centrifugal pumps are manufactured to ASME BPE specification criteria. All product contact components on the S200 are machined from wrought <5% ferrite level, 316L stainless steel and feature a 20 Ra product contact surface finish. Material heat numbers are available on all product contact components.
Designed for heavy-duty, high-efficiency applications, sanitary centrifugal pumps provide exceptional corrosion resistance. Impeller and shaft are one piece, which connects directly to motor shaft; eliminating such problems as vibration, short bearing life, high NPSH requirements, high seal maintenance, poor tolerance, and adverse operating conditions.
The versatile Series close-coupled sanitary centrifugal pump offers strong performance and competitive price/value within the lower spectrum of heavy-duty, centrifugal pump applications. Sanitary centrifugal pumps can be installed in a series without fear of seal failure from elevated inlet pressures, even with viscous products.
The APV W+ pump series if based on a unique hydraulic design that ensures maximum efficiency allows for the highest hygienic standards and reduces noise and vibration. The W+ range consists of 16 standard models with pressure and flow capacities to 217psi and up to 1,760gpm. A number of special versions are available, including the Wi+ inducer pump for low NPSH applications and the Ws+ self priming unit designed to handle CIP return and other fluids with entrained air and foam.
An Inducer is an axial flow impeller with blades that wrap in a helix around a central hub. The inducer rotates in a close-fitting housing to provide a "booster" effect in front of the main impeller.
The inducer pump is the alternative to changing the process design when NPSH availability is low. The inducer boosts the inlet pressure, and the risk of cavitations is correspondingly reduced (the NPSH required typically drops by 50-70%). When the risk of cavitations disappears, so does the risk of a large number of operational disturbances that would otherwise result - such as excessive noise, energy loss, product damage and unnecessary wear on the pump. Low suction head is a common "problem" in miscellaneous applications, e.g. when pumping products with low boiling points or in processes that involve vacuums.
The Wi+ is unique among inducer pumps, since the NPSH requirement is kept to a minimum throughout its entire operating range. The inducer further enables the Wi+ pump to handle viscous or gaseous products beyond the range of other centrifugal pumps.
The self-priming Ws+ is designed to handle CIP return and other fluids with entrained air and foam. The unique design reduces the energy consumption and noise of traditional liquid ring pumps by using a high efficiency impeller that can be trimmed to match a specific duty. The Ws+ employs a built in eccentric air screw to form the liquid ring required for its self-priming capability.

The equipment shall be capable of developing the required head at rated capacity for continuous operation.
All Centrifugal Pumps shall have a drooping characteristics curve, with the head continuously increasing with decreasing flow to maximum head at zero flow and the pumps shall preferably be non-overloading type beyond rated duty point. The characteristics curves of each set of pumps shall match each other for equal load sharing in case of parallel operation and such pumps shall be identical and all parts shall be fully interchangeable.
The ash slurry sump geometry and configuration shall be such as to minimise ash settlement, formation of vortices and air entrainment in the slurry as this may affect the operation of the slurry disposal pumps. To minimise the ash settlement adequate number of high velocity water jetting nozzles shall be provided in the slurry sumps.
The fly ash slurry concentrations under this mode of operation shall be decided, considering the rated capacity of the extraction system. To maintain the concentration limit and to run the ash slurry disposal pumps efficiently a provision shall be made for make-up water pipe connections complete with motor operated gate valves and manual gate valves.
Minimum 10% margin shall be considered for ash slurry pump sizing over and above the total slurry disposal head requirement comprising the straight pipe line frictional loss and bends loss. The value of the constant ‘C’ in William-Hazen equation shall be considered as 140 for calculating the system head.
An additional flow of 100 m³/hr (continuous) shall be considered on ash slurry pump capacity to take into account sludge disposal from clarifier units to be pumped by ash slurry disposal pumps to the disposal area. Bidder may take advantage of this additional quantity of sludge (the density of solids in sludge may be taken as 1.1 and the concentration as 5%) while arriving at ash slurry concentration for the combined ash disposal pumps. Apart from the working streams one standby and one maintenance standby shall be provided for the ash slurry disposal system.
The slurry pumps shall essentially be slow rpm pumps. The rotational speed of the impeller at design point shall not exceed 1000 rpm. The first stage of slurry disposal and transportation pumps shall be provided with variable speed hydraulic coupling of robust design for setting the optimum operating speed of the pumps based on actual site requirements after the system is installed. Minimum (+) 10% and (-) 45% speed variation with respect to speed at rated design point shall be provided in the first stage of combined ash slurry disposal pumps and ± 20% for bottom ash transportation and BA overflow water pumps.

To minimise the drive losses in the first stage of slurry disposal and transportation pumps, a constant speed reduction gear box shall be provided. The gear boxes to be employed shall be suitable for heavy duty application and of such reputed make which have proven established record of trouble free service under heavy load transmission duties.
For the subsequent slurry disposal and transportation pump stages, the drive shall be transmitted through belt drive arrangement. If in future, the operating speed of these pumps is also required to be changed, the Owner intends to carry out this change by replacing the existing belt-pulley with a pulley of different diameter to allow a future variation of ± 10%. Pump and motor layouts in the pump house shall be accordingly decided to take care of this requirement.
Continuous motor rating (name plate rating) at 50°C for ash slurry pumps shall have at least 20% margin above the maximum load demand of the driven equipment at the rated duty point. The maximum load demand shall be calculated considering slurry density, efficiency of pump when handling slurry and the complete drive losses in the transmission (fluid coupling, gear box, etc.). For selecting the motor, the maximum pump efficiency to be considered shall be 70%. To ensure interchange ability, all the pumps & motors of the pumping streams shall be of similar rating and the pumps shall be designed for + 10% and – 45% speed variation.
Pumps shall be single stage, end suction design provided with heavy duty impellers suitable for highly abrasive duty application. All the wear parts of pumps, impellers and liners etc. shall have a minimum guaranteed life of 8000 hrs. of operation. Provision shall be made for adjustment to take up wear by axial movement of the shaft. The seals shall be water flushed packed glands, fed from an external clean water supply source. The impeller tip speed at the rated parameters shall not be more than 1676 metres/min. Bidders shall make selection of the pump size such as to limit the tip speeds to above specified limits.
