The Evak 80EUBM-5.20T is a 3″ lightweight submersible dewatering pump for high-volume site drainage. 1.5 kW / 2 HP three-phase 400V motor, semi-open high chrome steel impeller, twin silicon carbide mechanical seals, stainless steel outer casing.

The larger 3″ discharge trades head for flow — 690 L/min max flow, 17 m max head. Three-phase power draws only 3.5 A at full load — ideal for larger site installations where 3-phase supply is available. Just 25.9 kg thanks to aluminium alloy construction.

Full Description

The Evak 80EUBM-5.20T is a 3″ lightweight submersible dewatering pump from the EUB-M series — the high-flow, three-phase variant of the 1.5 kW range. A 1.5 kW / 2 HP three-phase 400V motor drives a semi-open high chrome steel impeller through a heat-treated AISI 410 stainless steel shaft, with the larger 3″ discharge tuned for volume rather than lift.

Compared with the 2″ 50EUBM-5.20T sibling, this pump delivers 690 L/min maximum flow (vs 500 L/min) at 17 m maximum head (vs 23 m) — the classic high-flow trade-off. Choose the 3″ version when you need to clear large volumes quickly at moderate lift heights: wide excavations, flooded yards, large sumps, and general high-volume dewatering on sites with 3-phase distribution.

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 (3.5 A) — ideal for sites with 400V 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″ discharge for high volume

Larger bore delivers 38% more flow than the 2″ 50EUBM-5.20T sibling — ideal when volume matters more than lift.

Three-phase advantage

Smoother start-up, lower running current (3.5 A), and better efficiency than the single-phase equivalent — ideal for sites with 400V distribution.

Applications

Wide excavation dewatering

Clearing large-footprint site excavations, wide trenches, and shallow-to-medium-depth foundations.

Flood water clearance

Rapid clearance of large volumes of standing flood water from yards, car parks, basements, and outdoor storage areas.

Mining & tunnelling

Dewatering shafts, tunnels, and underground workings where high volume matters more than lift height.

Industrial dewatering

Factories, plants, and yards with 3-phase power distribution needing reliable high-volume dewatering capability.

Cement industry & river intake

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

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. High-flow, not high-head — maximum lift is 17 m. For higher head duties on 3-phase, see the 50EUBM-5.20T (23 m max) or 50EUBM-5.30T (26 m max). Free passage 9 mm — not a sewage pump. Maximum liquid temperature 40 °C.

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.
