The Evak 80EUBM-5.50T is a heavy-duty 3″ submersible dewatering pump for major site drainage. 3.7 kW / 5 HP three-phase 400V motor, semi-open high chrome steel impeller, twin silicon carbide mechanical seals, stainless steel outer casing.

The heavy-duty variant of the 3″ range — 900 L/min max flow at 30 m max head. Nearly matches the flow of the 80EUBM-5.30T but adds 7 m of extra lift. For deep excavations, major civil engineering dewatering, and demanding continuous-duty industrial installations. Aluminium alloy construction keeps weight at 35.6 kg despite the extra motor size.

Full Description

The Evak 80EUBM-5.50T is a heavy-duty 3″ submersible dewatering pump from the EUB-M series — a significant step up in capability over the 2.2 kW models. A 3.7 kW / 5 HP three-phase 400V motor drives a semi-open high chrome steel impeller through a heat-treated AISI 410 stainless steel shaft, delivering serious flow and head simultaneously.

This is where the EUB-M range transitions from contractor-scale to genuine industrial and commercial capability. Compared with the 2.2 kW 80EUBM-5.30T, the extra 1.5 kW of motor delivers 900 L/min at up to 30 m of head — 200 L/min more flow AND 7 m more lift. Free passage also opens up to 10 mm to handle slightly larger site debris.

The pump uses aluminium alloy construction (AlSi7Mg discharge, covers and seal bracket), making it 14–17% lighter than an equivalent all-cast-iron dewatering pump. Stainless steel AISI 304 outer casing, motor frame and strainer resist corrosion in aggressive site environments, while an EN-GJL-200 cast iron pump casing provides structural strength where it matters. A double mechanical seal — upper CA/CE, lower SiC/SiC — runs in an oil bath for reliability. IP68 sealing allows submersion to 20 m, and the KLIXON auto-reset thermal protector guards the Class F insulated motor against overload. Three-phase operation delivers smooth start-up and lower running current (9.5 A) — well suited to sites with dedicated 3-phase distribution.

Construction

Semi-open high chrome impeller

High chrome steel semi-open impeller resists abrasion from suspended solids and sand-laden site water.

Stainless steel jacket

AISI 304 stainless steel outer casing, motor frame, and suction strainer for corrosion resistance on aggressive sites.

Aluminium alloy body

AlSi7Mg discharge, upper cover, motor cover, and seal bracket — 14–17% weight saving vs all-cast-iron equivalents.

Twin silicon carbide seal

Double mechanical seal — upper CA/CE, lower SiC/SiC — in an oil bath for maximum reliability.

3″ heavy-duty output

3.7 kW motor delivers flow AND head simultaneously — suits demanding jobs where lower-power pumps fall short on one axis.

10 mm free passage

Enlarged solids clearance handles typical construction site debris — grit, small stones, and organic material.

Applications

Major civil dewatering

Deep foundations, cofferdams, underpass excavations, and infrastructure projects requiring sustained high-volume, high-lift dewatering.

Mining & tunnelling

Deep shafts, active tunnel drainage, and underground excavations where head requirements exceed 2.2 kW pump capability.

Industrial & commercial installations

Factories, plants, and processing facilities requiring reliable heavy-duty dewatering on 3-phase power.

Major flood response

Rapid clearance of large volumes of flood water from car parks, industrial estates, and infrastructure sites.

Cement industry & river intake

Handling abrasive slurries and heavy-duty river-intake duties — the high chrome impeller resists wear from sand and silt at scale.

Three-phase 400V supply required — manual operation only. Float-switch auto operation is not available on the three-phase model; use with a suitable motor starter and level controller. 3.7 kW motor requires appropriate cabling, isolation, and protection. Free passage 10 mm — not a sewage pump. Maximum liquid temperature 40 °C. Not suitable for aggressive chemicals or hydrocarbons. For lower duty (2.2 kW), see the 80EUBM-5.30T. For 4″ discharge at same 3.7 kW, see the 100EUBM-5.50T.

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.
