Chamber

Pump chamber with optimised geometry for deposit-free operation. Chamber component with finning for high inherent stability and anti-buoyancy. The inlets are freely configurable. Two lifting eyes are integrated for attaching the lifting accessory. The upward curved pump chamber cover can be walked on and can be loaded with max. 200 kg. For the building installation, the pump chamber is equipped with a floor fixation.

Pipework

• Discharge pipe with flange connection on the pump side
• Gate valve
• Surface coupling
• Non-return ball valve (integrated in the surface coupling)

• The pump chamber for two pumps has separate pipework for each pump. They therefore also have two discharge ports. Provide the Y-piece on-site.
• The maximum ground water level above the bottom edge of the chamber is 500 mm.
