Line-Shaft Turbine Pumps
Construction Features
- Electric Motor Drives:
Use standard solid shaft flange mounted electric motors fitted to heavy duty thrust assembly incorporating non-reverse ratchet, heavy duty grease lubricated thrust bearing and flexible shaft coupling.
- Right Angle Gear Drives:
Used for P.T.O. shaft diesel or petrol engine powered pumping applications and are available in a range of speed ratios and power ratings. Gearboxes are flange mounted on the thrust assembly.
- Discharge Heads:
Incorporating flanged outlet connection, water lubricated shaft packing gland and machined spigotted mounting flange for thrust assembly mounting.
- Column and Shafting:
Column pipe is mild steel with either screwed or flanged connections in 1.5 or 3 metre sections depending on pump running speeds and bearing spacing requirements. Stainless steel drive shaft is supplied in 1.5 or 3 metre lengths with stainless steel couplings.
- Shaft Bearings:
Water lubricated spiral grooved neoprene rubber shaft bearings are supported by rigid bronze bearing spiders fitted at each column pipe coupling giving minimum spacings of either 1.5 or 3 metres over the entire drive shaft.
- Pump Stage Casings:
Cast iron construction (option of cast bronze) incorporating diffuser vanes and rigid shaft support bearings. These tandem bronze and neoprene rubber bearings combine to give accurate shaft support and abrasion resistance.
- Impellers:
High efficiency cast bronze impellers are hydraulically and statically balanced for vibration free operation. Tapered stainless steel collets guarantee positive locking of impellers to shaft.
- Inlet Strainers:
Choice of conical or basket type inlet strainers are available in heavy galvanised mild steel or stainless steel to suit installation type and water quality.
