SEEPEX has introduced its Drive Joint Access (DJA) technology for open hopper pumps for dewatered and thickened sludges, allowing in situ access in just 11 minutes.

The company says that the DJA technology reduces maintenance time by up to 75% and costs by up to 90% and has already been installed at Thames Water, Anglian Water, United Utilities and a wastewater treatment site in Ireland.

These types of pumps are typically located in tight spaces often obstructed by pipework and valves, making access difficult and maintenance a lengthy process.

Seepex had previously designed a feature that enables the rotor and stator to be removed from the front end of the pump without dismantling the whole unit. It simply translated the concept to the back end of the pump. The DJA is a detachable joint casing mounted on rollers, situated between the feed hopper and the pump-bearing housing. It enables engineers to reach the drive-side joint area, mechanical seal, plug-in shaft and gear box drive within just 11 minutes.
