Description
- Pump type 'MA' are horizontal, centrifugal self priming pumps with built in deaerating 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 bearing at both ends. these bearing 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.
Technical Data
- Discharge indicated in the water at barometric height of 760mm mercury and at a temperature 30°C .
- Power indicated is that absorbed at the pump shaft when pumping liquids having specific gravity of 1.0 and viscosity cSt.
- Direction of rotation is clockwise seeing from the drive end. Reverse rotation also available on request
- Maximum permissible speed is 1800 R.P.M.
- Maximum suction lifts is 7 mtrs. Depending upon the duty point. Capacity reduces over 4 mtrs. Suction lifts.
- Before starting the pump for the first time it must be filled with liquid to ensure priming.
- Tolerance on discharge is ± 10% at rated head and rated R.P.M.
- No subsequent external priming is necessary.
