The Evak Hippo 65-550 (400V) is the flagship of the Hippo DN65 range — 4.1 kW / 5.5 HP three-phase, recessed vortex impeller, 65 mm free passage and a DN65 flanged discharge for guide rail installation. 1,200 L/min and 22.5 m of head, rated 500 L/min at 15 m — the most lift and the most volume in a 2.5″ Hippo.

Built for the biggest sewage pump stations the DN65 format serves: larger developments, commercial and industrial sites, and treatment works with long or steep rising mains. The 65 mm passage takes the solids and rag a 50 mm pump blocks on. Cast iron pump body, stainless steel motor housing, EKK Eagle Burgmann double mechanical seal. Manual operation for panel control. 10 m cable.

Full Description

The Evak Hippo 65-550 (400V) is the top of the Hippo DN65 range. The model code says it: 65 for the 65 mm discharge and free passage, 550 for 5.5 HP. A 4.1 kW 2-pole three-phase motor drives a recessed vortex impeller to 1,200 L/min and 22.5 m of head, with a rated duty of 500 L/min at 15 m. It’s the pump for the station that has to push a long way uphill and still keep pace with a big inflow — a rising main over a hill, a deep chamber on a sloping site, or a commercial development where morning demand arrives all at once.

The 65 mm free passage is the reason to buy it over a 50 mm pump. Raw sewage carries rag, wipes and solids that wrap around a smaller impeller; the DN65 vortex design keeps the impeller recessed out of the flow so solids pass through the volute without touching it. The DN65 flanged discharge (DIN PN10/16) bolts to a QD-65 quick-discharge coupling for guide rail installation, so the pump lifts out for service without anyone entering the chamber.

Cast iron pump body and volute, stainless steel motor housing, and an EKK Eagle Burgmann double mechanical seal (carbon/ceramic upper, silicon carbide lower) in an oil bath with NBR lip seal. Class F insulation, IP68, auto-reset thermal protector, ball bearings. Three-phase motor drawing 9.1 A, no capacitor, no float — supplied manual for control from a panel. 10 m cable. 43.7 kg — davit or hoist only.

Construction

65 mm vortex impeller

Recessed vortex design passes 65 mm solids and rag through the volute without contact — the difference between a sewage pump that blocks and one that doesn’t.

DN65 flanged discharge

DIN PN10/16 flange for a QD-65 quick-discharge coupling on a guide rail, or direct to a flanged riser. Lift out for service without entering the chamber.

Cast iron pump body

FC200 cast iron volute and casing for long life in raw sewage.

Stainless motor housing

Stainless steel motor housing over a Class F dry-type motor with auto-reset thermal protector and ball bearings. IP68.

EKK Eagle Burgmann double seal

Carbon/ceramic upper and silicon carbide lower mechanical seals in an oil bath with NBR lip seal — a named, serviceable seal set, not a generic one.

Three-phase manual motor

400V three-phase, 9.1 A, no capacitor, no float — wired to a control panel with level probes or floats. DOL or star-delta start to suit the supply.

Applications

Large pump stations

Duty/standby sewage chambers for housing developments, apartment blocks, hotels, schools and industrial estates.

Long or steep rising mains

22.5 m of head for mains that climb to a distant sewer connection, cross a ridge, or serve a chamber well below the outfall.

High-inflow sites

1,200 L/min keeps a station ahead of peak demand and storm inflow without running continuously.

Treatment works transfer

Raw influent and sludge transfer on small municipal and larger packaged treatment plants.

Replacement duty

Direct swap for existing DN65 guide rail pumps — check the coupling, rail centres and panel rating before ordering.

Maximum liquid temperature 40 °C. Maximum submersion 10 m. Maximum 20 starts per hour. Manual operation — no float switch fitted. Three-phase only; requires a control panel rated for 9.1 A per pump, and check rotation direction on commissioning. 43.7 kg — use rated lifting gear. Flanged discharge — order the QD-65 coupling or a flange adaptor with the pump. Not for potable water or corrosive fluids (see Stainox range). For 76 mm free passage and up to 1,600 L/min see the Hippo 80 series.

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.
