Wastewater pump – robust and reliable solution for handling unclean water

A wastewater pump is a pump designed to handle wastewater – water that can contain anything from sand, grease and sludge to larger solid particles such as gravel and waste. The pump is typically used in situations where it is not possible to divert the wastewater with a natural fall or where temporary bypass pumpings are necessary due to construction work, sewer renovation or downtime.

At RH Pumper, we work with wastewater pumps that are portable, reliable and ready to use – whether the job is planned or emergency.

Technical function

A sewage pump works by creating a negative pressure that draws wastewater into the pump and out through the discharge pipe. Depending on the type, the pump can be self-priming, submersible or connected to a motor or electrical solution.

Most wastewater pumps are equipped with a free passage that allows particles and solids to pass through without clogging the pump. For larger particles, models with grinders or specially designed impellers are available.
