More about this product

Full Description

The Evak Hippo 50-50 (110V) is the entry-point in the Hippo range, specifically built for the UK construction market with a 110V CTE motor winding for use with standard building-site transformers. A 0.37 kW / 0.5 HP 2-pole single-phase motor drives a vortex impeller through a heat-treated stainless steel shaft, supported by NTN long-life ball bearings.

The 50 mm full free passage vortex impeller is designed to handle raw sewage and heavy solids without clogging — a genuine step up from the 35–40 mm free passage typical of comparable-sized pumps. Combined with the EN-GJL-200 cast iron pump volute, this makes the Hippo 50-50 a workhorse for site sump duty, temporary sewage transfer, and flood-water management where standard 230V mains supply isn’t available.

The motor housing is AISI 304 stainless steel with a PA66+30GF glass-reinforced nylon motor cover — the cover material used across the 0.5–1 HP Hippo range for reduced weight without compromising strength. Twin EKK Eagle Burgmann mechanical seals (upper Ca/Ce, lower SiC/SiC) run in an oil chamber with an NBR lip seal. Klixon auto-cut thermal protection safeguards the motor. Supplied as automatic with float switch, or manual for use with external level controllers.

Construction

Cast iron pump volute

EN-GJL-200 cast iron pump casing, impeller, oil chamber, bracket, and seal housing — heavy-duty grey iron for long service life in abrasive conditions.

Stainless motor housing

AISI 304 stainless steel motor housing over the stator, with AISI 410 heat-treated stainless shaft. Nylon 6 handle, PA66+30GF glass-reinforced nylon motor cover.

50 mm vortex impeller

Recessed vortex design giving full 50 mm free passage — handles typical sewage solids and stringy material without clogging.

Twin silicon carbide seal

EKK Eagle Burgmann double mechanical seal — upper Ca/Ce, lower SiC/SiC — running in oil chamber with NBR lip seal.

110V CTE construction

110V centre-tapped-earth motor winding for use with UK site transformers — 3.3 kVA transformer supports one pump; 5 kVA supports two.

Auto or manual operation

Available with pendant float switch for automatic sump duty, or manual for use with an external level controller.

Applications

Construction & groundworks

Site sump duty, temporary sewage transfer, foundation dewatering — wherever 110V CTE supply is available and 230V mains isn’t.

Flood emergency response

Emergency dewatering with generator or transformer supply — portable, fast to deploy, handles debris-laden flood water.

Temporary sewage transfer

Small-scale sewage transfer where a permanent installation isn’t required or the mains supply is unsuitable.

Basement & cellar drainage

Domestic or light-commercial basement sumps — particularly on temporary refurbishment or building sites.

Rental fleet

110V CTE variant makes this the go-to pump for tool-hire fleets serving the UK construction market.

110V CTE supply required — requires a 3.3 kVA or 5 kVA site transformer. Not suitable for direct connection to 230V mains — use the Hippo 50-50 230V variant for domestic supply. Maximum liquid temperature 40 °C. Maximum submersion depth 10 m. Not for potable water. For higher flow, see the Hippo 50-75 (0.75 HP) or Hippo 50-100 (1 HP) at 110V. For corrosive fluids, see the Evak Stainox 5.05 (316 stainless steel construction).

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.
