After seeing the benefits offered by
NOV Mono’s EZstrip transfer pump
at one of the company’s UK
roadshows last summer, Thames
Water has installed one to improve
efficiency and reduce downtime at
Beckton sewage treatment works.

The EZstrip progressing cavity
pump, which has been mounted
vertically, has been installed in a
pump station to transfer returned
sludge to the buffer tanks at a
capacity of 90m3/h and a delivery
pressure of 4 bar.

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

The pump’s chamber has a twopiece
design which can be opened in
less than 1min, suction chamber and
rotating parts de-ragged and the
chamber reassembled with a spanner
and an Allen key. The operation
takes less than 2.5min, depending on
the severity of the rag blockage.

The pump can be installed into
new plants or retrofitted to existing
Mono Compact C installations. No
electrical disconnection is required.
