More about this product
Overview
The EVAK Drainox 750 (110V) is the mid-range submersible site drainage pump in the Drainox family – built for arduous dewatering applications where meaningfully more flow and head than the 400 are needed, but the pump still has to be portable. Contractor-grade throughout – stainless steel strainer base, cover and handle over an FC20 cast iron pump housing, with a highly abrasion-resistant Hytrel vortex impeller and SIC/SIC double mechanical seal in an oil chamber. This 110V model is intended for site use via a transformer and is available in both auto and manual configurations.
When to Choose the 750 Over the 400
The 750 delivers 300 l/min and 15m head, against 225 l/min and 11m on the Drainox 400 – clearing larger volumes faster and pumping further from the source. It shares the same 2″ discharge, 5mm free passage and portable form factor.
For smaller sumps, drainage pits and lighter site duties, the Drainox 400 is usually sufficient.

Applications
Larger construction site dewatering, arduous site drainage, trench pumping, and permanent sump installations. The 110V version is intended for site use via a transformer, making it well suited to construction and hire fleet duties. Its higher flow and head suit longer hose runs, uphill discharge and larger volumes than the Drainox 400 can handle.
FAQs
110V is the standard site-safety voltage in the UK, run via a transformer – suited to construction sites and hire fleet use rather than domestic mains.
Choose auto (float switch fitted) for unattended sump or drainage pit installations where the pump needs to cycle on and off with water level. Choose manual for operator-controlled dewatering, where you’ll switch the pump on and off yourself.
The Drainox is a heavy-duty site drainage pump with a 5mm free passage and cast iron construction – built for arduous dewatering. The Residox is a puddle sucker designed to pump right down to 1mm above the floor, better suited to flood recovery than site drainage.
The Drainox 1500 delivers 470 l/min and 19.5m head – the appropriate choice where flow rate is the limiting factor. Note the 1500 is not available in 110V, so you’ll need 230V mains or 400V three-phase power on site.

Frequently Asked Questions
Quick answers to common questions about the EVAK Drainox 750 – 110v. For technical specifications, see the product details above; for sizing or installation advice, contact our team. If you have any other questions, we're happy to help.
What is a submersible pump?
A submersible pump is designed to operate fully submerged in the liquid it is moving. The motor is sealed inside the pump body and cooled by the surrounding water. Submersibles are used for drainage, sewage, septic tanks, deep wells and boreholes, and for raising water from sumps, cellars and floodwater. Many stocked at Anglian Pumping handle solids in suspension.
Can submersible pumps handle solids and sewage?
Yes – some submersibles are designed for clean water only, others handle solids up to 50 mm or full raw sewage. Anglian Pumping stocks ABS, BBC, Flygt and T-T Submersibles ranges that include vortex, single channel and grinder impellers for different solids handling requirements. Always match the pump to the maximum solid size and the type of effluent it will see.
When should I use a submersible pump instead of a surface pump?
Use a submersible when the water level is more than around 8 metres below the pump installation point – surface pumps cannot self-prime beyond that depth. Submersibles are also better when the liquid contains solids, when noise must be minimised, or when the pump needs to operate in confined spaces such as sumps and chambers where a surface pump would not fit.
