Thames Water has installed
an EZstrip maintain-in-place
pump, from NOV Mono to
improve efficiency and cut
downtime at its Dorking
sewage treatment works.

Previous equipment that
transferred sludge from the
primary settlement tank into
a picket fence thickener, was
causing significant downtime.

Mono’s EZstrip pump, which
can be stripped down and
maintained in 30min,
provided the solution.

Gavin Parker, sewage
works operator at Thames
Water, says the Mono EZstrip
sewage pump has significantly
reduced maintenance and
downtime and that because
the pump requires no
dismantling space, it was
easily installed into space
occupied by the previous
pump with room to spare.

The range has a capacity of
up to 165m3/h and 12 bar
pressure and is available in
cast iron or stainless steel.
