The Tsurumi OM3 submersible drainage water pump is a strong and efficient pump engineered in 304 stainless steel and thermoplastic.
Excellent flow and pressure is generated by the Tsurumi OM3 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 floats 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 hard-wearing twin 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 Tsurumi OM3 in 230 volts 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).
Manual version is supplied without the tubular float switch.
Auto version comes with the tubular float switch for fully automatic operation.
The industrial has a female BSP outlet (for fitting rigid waste pipe) but a plug is not supplied. 110 volt pumps are supplied as industrial.
Offered with a 3 year guarantee, the Tsurumi OM3 range of submersible pumps are the ideal choice.
Please note that the current version of this model is now the OMA5.

Was a pleasure to deal with Henry Pumps. They were ever so helpful. When our Tsurumi OMA pump broke down they got me the new one the following morning. Thank you.
