Clean wastewater pumps without fiber collection

Impellers are frequently blocked by sanitary and other waste products that are not intended for removal in wastewater. Blockages of this kind can be a costly aspect of wastewater handling and have to be removed manually. This is why its helpful to have SIRIUS soft starters, they can help reduce this manual effort when your pumps get blocked.

Automatic pump cleaning with the SIRIUS 3RW55 soft starter

To avoid deposits on pump blades and reduce downtime due to blockages, time-consuming and costly cleaning of pumps on a regular basis is necessary. However, when using the SIRIUS 3RW55 soft starter's pump cleaning function, you get an integrated measuring technology that detects soiling early and triggers automatic cleaning of the pump to prevent these blockages.

How does the SIRIUS 3RW55 soft starter prevent pumps from getting blocked?

The SIRIUS 3RW55 can evaluate the motor current and active power. If defined threshold values have been exceeded, an increased amount of soiling can block the pump. When this happens, the pump cleaning function of the soft starter offers the option of automatic cleaning. During the cleaning solution, the pump alternates between forward and reverse operations at rated-speed or reduced speed and therefore outputs a maximum possible torque on the motor. This loosens dirt deposits from the impellers, lowering maintenance costs and increasing your plant availability.
