The Evak Hippo 50-75 (230V) is the 0.75 HP mid-range sewage pump in the Hippo family, in 230V single-phase for standard domestic mains supply. 0.55 kW / 0.75 HP single-phase motor, 2″ discharge, cast iron pump body with vortex impeller and 50 mm free passage.

Genuine step up from the 50-50 — 390 L/min max flow at 10 m max head (vs 330 L/min and 8 m). Suits medium-duty sewage pits, deeper basement sumps, and light-commercial installations where the 0.5 HP variant is under-specified but a 1 HP pump is overkill.

More about this product

Full Description

The Evak Hippo 50-75 (230V) is the mid-range sewage pump in the Hippo family, built for standard UK domestic and light-commercial mains supply. A 0.55 kW / 0.75 HP 2-pole single-phase motor drives a vortex impeller through a heat-treated stainless steel shaft, supported by NTN long-life ball bearings.

Compared with the 0.5 HP 50-50, this variant delivers 390 L/min at up to 10 m of head — 18% more flow and 25% more lift, at the same 2″ discharge and 50 mm free passage. Suits medium-duty sewage pits, deeper basement sumps, and installations where discharge runs are long enough that the 50-50 struggles to maintain flow at the delivery point.

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. The motor housing is AISI 304 stainless steel with a PA66+30GF glass-reinforced nylon motor cover. 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.

Auto or manual operation

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

Vertical or horizontal outlet

Vertical PT-threaded outlet for portable and hose-tail installations, or horizontal flanged (Q-type) outlet for guiderail auto-coupling on permanent installations.

Applications

Medium-duty sewage pits

Off-mains housing, holiday parks, and rural properties with multiple bathrooms or longer discharge runs to the septic system.

Deeper basement & cellar sumps

Permanent sump installations in basements and cellars with greater lift requirements than the 50-50 can handle reliably.

Small sewage stations

Small-scale sewage transfer stations serving properties with total flow requirements in the 200–400 L/min band.

Light-commercial installations

Small offices, cafes, workshops, and light-commercial premises with permanent sewage pit installations on 230V mains.

Rainwater management

Below-ground rainwater sumps at greater depth or with longer discharge runs — 50 mm free passage handles leaf debris without clogging.

Maximum liquid temperature 40 °C. Maximum submersion depth 10 m. Automatic float-switch operation available. Not for potable water. For UK construction site use with 110V CTE site transformer, see the Hippo 50-75 110V variant. For 3-phase supply, see the Hippo 50-75 400V. For lower duty (0.5 HP), see the Hippo 50-50 230V. For higher flow (1 HP), see the Hippo 50-100 230V. For corrosive fluid duties, see the Evak Stainox range.

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.
