Industrial Pumps and Motors
Units for fixed installations: presses, benders, test rigs, clamping and lifting circuits driven by an electric motor. Duty is usually continuous and the pressure setting rarely changes.
Features
- Sized on continuous duty rather than peak, because a fixed installation often runs the same cycle for a whole shift.
- Noise matters indoors, so vane and screw types appear where a piston pump would be specified on a machine.
- Bell housings, flexible couplings and tank-top mounting kits are part of the order, not an afterthought.
- Pressure-compensated variable pumps cut standby power on circuits that hold load for long periods.
- Hot running oil in an enclosed pump room usually means the heat exchanger and reservoir need reviewing at the same time as the pump.
Specifications
| Figure | Typical range | Unit | Why it matters |
|---|---|---|---|
| Displacement | 40 | cm3/rev | fixes flow at the electric motor's synchronous speed |
| Drive motor power | 7.5 - 45 | kW | checks that flow at pressure is inside the available power |
| Working pressure | 160 | bar | set once on a fixed rig, so it must be right |
| Control type | pressure compensated, remote vent | decides standby power and heat generation | |
| Mounting | bell housing to flange motor | alignment error shows up as a failed shaft seal |
