Launched in February, Mono NOV’s revolutionary ‘Maintain in Place’ EZstrip pump has taken the industry by storm, with a video of the pump being de-ragged in just 2 ½ minutes becoming a surprise internet hit.

The sought after EZstrip video has been featured on numerous industry websites and e-bulletins, and can also be seen on Mono’s website. It shows just how easy the EZstrip makes de-ragging and maintenance of a PC pump – using just spanners and an Allen key.

Nichola Somerville, Mono’s group marketing manager, commented: “The reduced maintenance time offered by the EZstrip is so revolutionary, it’s almost unbelievable which is why we needed to produce a video demonstrating just how quickly it could be de-ragged in place in real time.

“Take up and viewing of the video has been overwhelming, which provides a real indication of the impact that this significant innovation is having on the industry.”

Mono’s new EZstrip pump was launched through a series of teasers on the Mono website including video clips of the pump in action and a competition.

The ‘EZ’ competition ran by Mono asked, ‘What can you do in two and a half minutes?’ for a chance to win £500 holiday vouchers. The competition winner was Mr. John Ellery of Aker Solutions E&C Ltd.     

EZstrip is the biggest leap forward in progressing cavity (PC) pump design for 30 years. It 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.

On average, the EZstrip can reduce the maintenance time needed to replace a rotor, stator, coupling rod and drive train by up to 95%. The average time to completely strip down a pump and replace the drive train elements can be one full day; the Mono EZstrip reduces this to just a 30 minute job.

The EZstrip 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.

The EZstrip pump 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 is also available.
