Mono claims big leap for progressing cavity pumps


“The biggest leap forward in progressing cavity (PC) pumps in 20 years”.

That’s the dramatic claim that Mono is making for its new EZstrip pump.

EZstrip has been specifically designed to provide a quick and easy way to disassemble, de-rag and maintain a PC pump in-situ, eliminating the costly maintenance and down time that servicing can often cause.

Commenting on the launch of the EZstrip, Simon Lambert, Mono’s general manager for Europe, said: “We surveyed our customer base in the wastewater industry to find out what common problems they were facing. The overriding response was that ragging was becoming a serious problem, primarily because more and more unsuitable items are finding their way into the sewers.”

Once the company had addressed the ragging issue, it realised the potential of the product to minimise the time and cost involved in every aspect of maintaining a PC pump. On average, says the company, the EZstrip can reduce the maintenance time needed to replace a rotor, stator, coupling rod and drive train by 95 percent. The average time to completely strip down a pump and replace the drive train elements is one full day; the Mono EZstrip reduces this to just a 30-minute job.

The new pump can be installed into new plants or retrofitted into existing Compact C installations. No electrical disconnection is required and suction and discharge pipes remain untouched.

It offers dry run protection and all operational parameters are unaffected. The model range has a capacity of up to 165m3/h and 12 bar pressure, and is available in either cast iron or stainless steel. WRAS compliant elastomers are incorporated into the manufacture of this pump and a pre-assembled drive train, with two-year warranty, is also available.
