Frequently Asked Questions
What is the Grundfos SEG pump designed for?
Grundfos SEG grinder pumps are submersible sewage pumps with an integrated grinder system. They are designed to grind destructible solids into small pieces so wastewater containing solids and fibres can be transported through smaller diameter pressure mains.
What does the model designation SEG.40.12.2.50B mean?
- SE – Grundfos sewage pump series
- G – Grinder system in the pump inlet (impeller type)
- 40 – Nominal diameter of outlet port (DN40)
- 12 – Code relating to output power (≈1.2 kW)
- 2 – 2-pole motor
- 5 – 50 Hz
- 0B – 400–415 V DOL supply voltage and starting method
What discharge connection does this pump have?
This pump is supplied with a standard DIN DN40 flange. Because it follows the DIN standard, compatible fittings, guide claws or accessories from Grundfos or other manufacturers can be connected to the outlet.
Where are SEG pumps typically used?
SEG pumps are ideal in situations where a gravity sewer is not available or practical, such as:
- Sparsely populated areas and villages
- Farm or rural installations
- Sites with large terrain level differences
- Pressurised sewer systems where small diameter mains are required
What installation options are available?
The SEG range is designed for two submerged installation types:
- Submerged installation on auto-coupling systems
- Submerged free-standing installation
Does the pump have motor protection?
Yes. Thermal switches are built into the motor windings to provide protection against overheating. These must be connected to a suitable control panel in accordance with Grundfos instructions.
How durable is the construction?
The pump is manufactured from wear-resistant materials including cast iron and stainless steel. A corrosion-resistant stainless steel clamp secures the motor to the pump housing and allows easy servicing of the unit.
What is the SmartTrim system?
SmartTrim allows simple adjustment of the impeller clearance without dismantling the pump, helping to maintain maximum efficiency throughout the pump’s lifespan.
Why choose a grinder pump?
A grinder pump enables wastewater to be pumped through small pressure mains where gravity drainage is not practical, making it suitable for rural properties and sites with long or rising discharge pipework.
Do you offer technical support?
Yes — we can help confirm compatibility with existing pipework, guide-rail systems and control panels. Call 01803 220416 for advice before purchase.
