Description
- Pump type 'M' are horizontal, non-self priming centrifugal pumps. The pumps are built as single stage or multistage pumps upto 10 stages. Suction branch is horizontal and delivery branch in vertical. The intermediate parts are designed to lead the water from the outlet of one impeller to the inlet of the adjacent impeller the minimum of friction resulting in high efficiency of the pumps. The rotor of the pump is supported by antifriction bearings at both ends except for pump series M 450K in which rotor is supported antifriction bearing at the drive end and bush bearing at the free end. Antifriction bearings are grease lubricated. Pumps are provided with stuffing box packing. Depending upon the application Mechanical seal can also be fitted.
Technical Data
- Discharge indicated in curves applies to liquid at barometric height of 760mm mercury and at a temperature 30°C .
- BHP indicated in curves is for specific gravity of 1.0 and viscosity cSt.
- Direction of rotation is clockwise seeing from the drive end.
- Maximum permissible speed is 1800 R.P.M. for all pumps except M 450K for which maximum permissible speed is 3000 R.P.M.
- Before starting, valve on suction side must be fully opened and valve on delivery side closed
- Before starting the pump 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.
Application
- Mining
- Irrigation
- Water Works Boosting Pressure in Water Mains
