Pump type ‘MA’ are horizontal, centrifugal self priming pumps with built in de-aerating lateral channel stage. Both suction and delivery branches are vertical so that liquid remains inside the pump 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 bearings are grease lubricated. The pumps are provided with stuffing box packing. Depending upon the application mechanical seal can also be provided.
Pump type ‘MA’ are designed for continuous operation handling only clear liquid, free from any suspended particles.

  • Tolerance on capacity± 10% at rated head and rated RPM.
  • Discharge indicated in the selection chart applies to water at barometric height of 760 mm mercury 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.
  • Direction of rotation is clockwise seeing from the drive end. Reverse rotation (designated by ‘RR’) also available request.
  • Maximum suction lift is 7 meters (including friction losses) depending upon the duty point. Capacity reduces over 4 meters. Suction lift.
  • Before starting, valve on suction side must be fully opened and valve on discharge side about half opened.
  • Before starting, the pump for the first time it must be filled with liquid to ensure priming.
  • No subsequent external priming is necessary.
