WHY IT WORKS

Built for the job

Dirty Water & Sewage Pump – 50mm Solids Handling Submersible Pump

The Evak Hippo 50 Sewage Pump is a heavy-duty, submersible sewage pump engineered for robust performance in foul-water, sewage and flood-water applications. With a generous solids-handling ability (50mm), automatic variants (110V or 230V) and a manual 400V (3 phase) option, it gives you flexible power options to match site conditions.

Construction and Durability

The Hippo 50 is built for demanding environments, using robust materials throughout to ensure long service life in sewage and dirty-water applications. Key construction features include:

  • Cast iron pump housing for strength and durability
  • Stainless or alloy motor and seal casing
  • Recessed vortex impeller for reliable solids handling
  • Double mechanical seals to protect the motor
  • Integrated thermal and overload protection

Rated for liquids up to 40°C and a maximum submersion depth of 10 metres, the Hippo 50 is well suited to typical domestic sewage temperatures and chamber depths.

Why Choose the Evak Hippo 50?

The Evak Hippo 50 is designed to deliver balanced performance, powerful enough for sewage applications, without unnecessary over-specification.

Key benefits:

  • 50mm solids handling, ideal for most domestic sewage systems
  • Reliable performance without the cost and complexity of cutter or grinder pumps
  • Well suited to steady operation in typical sump installations
  • Excellent value for money for domestic and light-commercial use

Sewage pumps are designed to run steadily rather than switching on and off in rapid cycles, so it’s important not to over specify. Choosing a pump that operates comfortably in the middle of its performance curve gives better reliability and longevity. The Hippo 50 provides a well-balanced level of power for installations where the head height and discharge distance aren’t excessive, making it an ideal choice for typical domestic and light-commercial sewage sumps.

This model offers excellent value for money. You get a pump that handles the needs of most household sewage applications without jumping to more expensive commercial-grade cutter/grinder units that many customers don’t require.

If greater flow capacity or head height is required, the Evak Hippo 75 or Evak Hippo 100 Sewage Pump (11m head) is a suitable upgrade.

Operational Details

  • Flow rate: 330 litres per minute
  • Maximum head: 7 metres
  • Solids handling: 50mm free passage
  • Liquid temperature: up to 40°C
  • Maximum submersion depth: 10 metres

Available versions:

  • 110V automatic (with float switch)
  • 230V automatic (with float switch)
  • 400V manual (3-phase)

The 110V and 230V models provide automatic operation for standard sump installations, while the 400V manual option offers greater control where required.

Horizontal or vertical discharge options are available, with horizontal discharge ideal for guide-rail installations.

HOW-TO

Which Hose Should I use with my Water Pump?

Layflat hose is very affordable but can kink. Depending on your use, you may be better using a reinforced suction delivery hose for your needs.

Suction delivery hose is ideal for pumping up stairs or over obstacles.

Jonathan Martin explains the differences to help you choose which hose is best for your scenario.

Common questions

Can the EVAK Hippo 50 pump sewage in a domestic chamber?

Yes. With a recessed vortex impeller, 50mm solids handling, 330 litres per minute and 7 metres head, it suits most household sewage chambers where the lift and pipe run are moderate, without the cost of a cutter or grinder pump. It is rated for liquids up to 40 degrees. Keep wipes, sanitary products and rags out of the system.

When should I choose the Hippo 100 instead?

When the lift or pipe run would push the Hippo 50 towards its 7 metre maximum head, where its flow falls away. The Hippo 75 is the next step up, and the Hippo 100 gives up to 480 litres per minute and about 11 metres head. Don't over-size: sewage pumps last longest working in the middle of their curve.

See: EVAK Hippo 100 Sewage Pump

Is the Hippo 50 automatic?

The 230V version (3-pin plug) and the 110V version are automatic, with a float switch; the float must rise for the pump to start. The 400V three-phase version is manual and can be used with a separate float switch.

Vertical or horizontal discharge?

Vertical discharge suits a pump standing on the chamber floor with the pipe rising straight up. Horizontal discharge is ideal for guide-rail installations. Both are offered in every voltage on this listing.

Is a hose tail included with the Hippo 50?

No. The pump comes with a 10m heavy-duty rubber cable, but the hose tail or pipe connector for its 50mm outlet is ordered separately to suit your pipework. Fix the cable to the discharge pipe, and do not let the end of the discharge pipe sit under water, or water will flow back when the pump stops.
