Pump type ‘A’ are horizontal, lateral channel, self priming pumps acting on regenerative principal. Both suction and delivery branches are vertical so that liquid remains inside the pumps even when the pump is switched off. This ensures priming of the pump. The rotor of the pump is supported by antifriction bearings at both ends. These bearing are grease lubricated. The pumps are provided with stuffing box packing. Depending on the application, mechanical seal can also be provided. Pump type ‘A’ are designed for continuous operation handling only clear liquid, free from any suspended particles.


Domestic. Transfer of liquid containing air, gas, marine, refrigeration, fuel oil etc.


Casing: Close grained cast iron.
Impeller: Bronze
Shaft: Stainless steel
Special material of construction also available on request.

  • Tolerance of capacity± 10% at rated head and rated RPM.

  • Discharge indicated in the selection chart apply to water barometric height of 760 mm mercury column and at a temperature of 300C.

  • Power indicated is that absorbed at the pump shaft when pumping liquids having specific gravity of 1.0 and viscosity of 1 CST.

  • Maximum permissible speed is 1800 RPM.

  • For standard execution maximum permissible temperature of the liquid is 600C. Hot water construction (designated by ‘H’) is also available for liquids with temperature between 600C.

  • For hot water pumps capacity will be reduced by approximately 10%.

  • Direction of rotation – clock wise seeing from the drive end. Reverse rotation (designated by ‘RR’) also available on request.

  • Maximum suction lift is 8 meters (Including friction losses) depending pan the duty point. Capacity reduces over 4 M. suction lift.

  • Before starting valves on suction and delivery sides must be opened.

  • Before starting the pump for the first time it must be filled with liquid to ensure priming. No subsequent external priming is necessary.
