The Tsurumi OM4 submersible drainage water pump is a strong and efficient pump in 304 stainless steel and thermoplastic. Excellent flow and head are produced from an energy-efficient 150-watt motor, which makes it ideal for many domestic and industrial applications, particularly in cellars and processing duties. It is also popular with water companies, who select it for its advanced features and reliability. The close, compact positioning of the optional, integral tube float switch (OMA3), is particularly suited to applications where a sump is narrow or where a traditional pendant type float’s operation could be fouled. Long-term, trouble-free operation is enhanced further with an integral vent valve to prevent air locking. The 403 stainless steel shaft is fitted with an ultra hardwearing double mechanical seal (inboard: silicon carbide-silicon carbide) – running in an oil chamber – and a semi-vortex thermoplastic impeller. Supplied with 10 metres of heavy duty rubber power cable.

Users of 230volts have the option to select from two versions: the “domestic” is supplied with a hose tail, a hose clip (for fitting to flexible discharge hose) and a 3 pin plug (fitted with a 5 amp fuse).

The “industrial” has a female BSP outlet (for fitting rigid waste pipe) but a plug is not supplied. 110volt pumps are supplied as “industrial”.
