More about this product

Full Description

The Evak Stainox 5.05 (230V) is the entry point to Evak’s fully cast AISI 316 stainless steel submersible sewage pump range. Manufactured by lost-wax casting for high dimensional accuracy, the entire pump — body, impeller, motor housing, cover, shaft, rotor, and handle — is 316 SS. A 0.37 kW / 0.5 HP 2-pole single-phase motor drives a vortex impeller through a shaft supported by long-life ball bearings.

The 35 mm free passage vortex impeller is designed for non-clogging operation with medium-concentration wastewater. Combined with Viton gaskets, O-rings, lip seal, and cable gland throughout, the Stainox 5.05 handles environments that would rapidly corrode a cast iron pump — making it the go-to option for chemical, pharmaceutical, food-industry, marine, and treatment-plant duties at the small end of the range.

This 230V single-phase model is available with automatic float-switch operation for unattended sump duty or manual operation for use with an external level controller. An SQS-50 series double mechanical seal — upper Ca/Ce, lower SiC/SiC by EKK Eagle Burgmann — runs in an oil chamber for reliability. Optional epoxy-based nano-coating and acid/alkali-resistant cable sleeve extend service life in the most aggressive environments.

Construction

Fully cast 316 stainless steel

Lost-wax cast AISI 316 SS throughout — pump casing, impeller, motor housing, cover, shaft, rotor, and handle. Full corrosion resistance in chemical and marine environments.

Vortex impeller (316 SS)

Non-clogging vortex design with 35 mm free passage — handles typical sewage solids without blocking.

Twin silicon carbide seal

EKK Eagle Burgmann SQS-50 double mechanical seal — upper Ca/Ce, lower SiC/SiC — running in oil chamber with Viton lip seal.

Viton throughout

All gaskets, O-rings, lip seal, and cable gland made in Viton (fluoroelastomer) — chemical- and temperature-resistant.

Auto or manual operation

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

Optional extras

Epoxy-based nano-coating, acid/alkali-resistant cable sleeve, and Quick Discharge Connection (QDC) available on request.

Applications

Chemical & pharmaceutical

Drainage of process water and effluent in chemical plants, laboratories, and pharmaceutical manufacturing.

Corrosive wastewater

Wastewater with corrosive contaminants that would attack cast iron pumps — industrial cleaning, plating, food processing.

Wastewater treatment plants

Small-scale treatment plant sumps, transfer stations, and effluent handling where 316 SS is specified.

Marine & coastal

Salt water bilge, harbour, and marina sumps where chloride corrosion is a concern.

Food industry effluent

Dairy, brewery, and food-processing effluent handling where hygiene and corrosion resistance are both critical.

Maximum liquid temperature 40 °C. Maximum submersion depth 10 m. Automatic float-switch operation available on this single-phase model. Not for potable water. For 3-phase supply, see the Stainox 5.05 (400V). For higher-flow duty at same materials, see the Stainox 5.10, 5.20, 5.30, 5.50, or 5.75. For non-corrosive sewage duties on cast iron, see the Evak Hippo 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.
