Frequently Asked Questions

What does the model number mean?

• EF – Grundfos effluent pump range
• 30 – 30 mm free passage
• 50 – nominal outlet port diameter (mm class)
• 11 – 1.1 kW motor output
• 2 – 2-pole motor
• 1 – single-phase motor
• 5 – 50 Hz
• 02 – 230 V direct-on-line (DOL) starting

What is a single-vane, semi-open impeller?

This design uses one main sweeping blade with a more open flow path than a traditional channel impeller. It helps fibres and small solids pass through with fewer places to snag, while still producing better pressure and efficiency than a vortex (free-flow) design.

Why choose this over a vortex or non-clog pump?

• Vs vortex: better efficiency and head, lower running cost, but not as wipe-proof
• Vs channel impeller: more forgiving with fibres and stringy material

Ideal for drainage/surface water with small impurities and effluent with fibres (e.g. laundries) where a balance of clog resistance and efficiency is needed.

What discharge connection does this pump have?

This pump is fitted with an RS2 2" threaded connection. A suitable adaptor can be used to connect to hose or fixed pipework as required.

Can model numbers be interchanged?

Yes, in some cases alternative EF codes can be used depending on duty and installation. Please call us for guidance.

What is the maximum installation depth?

Maximum installation depth is 7 m.

Do I need a control panel for this 230V single-phase pump?

Yes. Single-phase submersible pumps require a dedicated control arrangement with correct start components and overload protection and must not be connected directly to the mains supply.

Do accessories come fitted?

No. Accessories are supplied separately.
