Description
SumpFlushHP Twin High-Performance Wastewater Pumping System
The SumpFlushHP Twin is a fully automatic wastewater pumping system designed for surface and groundwater drainage where gravity-fed solutions are impractical or uneconomical. The system uses twin high-powered submersible pumps to lift water to a higher discharge level.
It is suitable for applications including car parks, car washes, basements, downpipes, and cavity membrane drainage systems, where reliable high-head pumping performance is required.
Powerful and Reliable Pumping Performance
- Designed to handle vertical lifts of up to 12 metres
- Flow rates up to 4 litres per second
- Twin pump configuration providing duty and standby operation
- Storage capacity of up to 65 litres depending on inlet depth
- Compact chamber suitable for space-limited installations
- Flexible inlet positioning to suit site requirements
System Construction and Discharge
The system is supplied with a polyethylene tank, automatic submersible pumps, and a solid, locking galvanised steel access cover rated to FACTA AA.
Discharge is via solvent-welded 1¼ inch Class E PVC pipework. Optional discharge reducer kits are available to increase the external discharge diameter to 1½ inch or 2 inch to help reduce friction loss.
Compliance and Optional Enhancements
For groundwater and surface water applications where inflow cannot be controlled, the use of a high-level alarm and battery backup system is recommended in accordance with BS 8102:2022 and PCA Guidelines.
A range of battery backup systems, alarms, and remote alert options can be specified to suit project requirements.
Typical Applications
- Basements and below-ground structures
- Residential extensions and outbuildings
- Commercial surface water drainage
- Installations where gravity drainage is not possible
Important Use Guidance
This system is not suitable for foul water applications. For foul water pumping solutions, specification advice should be obtained prior to selection.
