After sucessfully introducing the Centrifugal Multistage Pumps, the design department of "PEW" has come up with a unique design of introducing a usage of closed type impellers and open type impeller into one single pump. this type of pumps are introduced as Centrifugal Self Priming Pumps. Due to combination of use of its large diameter centrifugal impellers and self priming pumps, the capacity of pump has increased when compared to other centrifugal pumps and does not need to do priming whenever the pump needs to start its cycle.
FEATURES
In these type of pumps, a combination of centrifugal closed impeller and a centrifugal self priming type open impeller are used together to achieve the high suction, high discharge characteristic.
Suction, intermediate stage pieces and discharge casings are clamped together by external tie bolts and sealed with gaskets.
Grease lubricated Antifriction Bearings are designed to meet the application requirements and are mounted on both sides.
Pump uses soft graphite lubricated asbestos packing. Special design of stuffing box with mechanical seal is available.
The suction and discharge ports are top vertical. The flanges are round and correspond to International standards.
The direction of rotation is clockwise when viewed from the driving end.
For suction more than 4m, the capacity reduces. Pump must be filled with liquid before they are started for the first time.
Details:
Sizes: 3" to 5"
Capacity: 2500 LPM

APPLICATIONS
Sea Water Bilge and Ballast in Marine applications
Fire fighting- Sprinkler and Jockey Pumps
LPG, Fuel Transfer and Unloading of Petroleum Products
Domestic water supply in High Rise Buildings
Transfer and Boosting of Corrosive Chemicals and Solvents in Process Plants
Being a pioneer in manufacturing of High Discharge Self priming Pumps, "PEW" now offers Horizontal Multistage Self Priming Pumps for use in places where high Discharge Self priming Pumps are not permitted / cannot be used. These pumps are basically used for industrial basis. These pumps have extremely low NPSH requirements and are particularly suitable for handling boiling liquids and other difficult applications.
This design is especially suited to handle liquids with estrained gases and liquified gases such as LPG.
Hozirontal Multistage Self Priming Pumps utilize the lateral channel principle. The Open, "Star" type impeller is hydraulically balanced, enclosed between the stage casings to form the pumping stage. These stages are mounted in series to give proportionally higher discharge pressures with constant capacities.
