ZJS100 Dredge Pump
The new ZJS100 dredge and jet pump is now entering production.
This is a 4" suction unit suitable for use on modern work
The unit benefits from the 14 years of experience built up from
before the design and build of the first Zip Pump. In particular
a new impeller design created as part of the AZ20 Suction Anchor
Pump development gives a wide performance range with and without
the simultaneous jetting capability selected.
The pump can both suction excavate and use the disruptor jet nozzle
at the same time.
Part of the impeller design benefits from the pre-swirl inlet filter
which also removes the need for a separate power water strainer.
Design History of the Dredge Pumps.
Before the creation of the first ZipPump the standard practice
was to build up ROV dredge pump systems which were comprised of
separate components brought together in a skid. A typical dredge
system is shown below. This particular unit was designed and manufactured
by Submarine Technology Ltd and supplied to Ametek. Other skid systems
were created by Genflo and Circle Offshore.
The Zip Pump which was conceived, designed and developed by R Q
Martin of DeersHill Engineeering Ltd. was a radical departure from
the current practice and produced a lightweight unitised pump system.
The prototype Zip Pump is shown to the right.
