REXROTH & Magnom prove the value of Pre Pump, Suction filtration

Variable Piston Pumps ‘VP Pumps’ along with more conventional pumps, have to ingest contaminants from the reserviour that pass return line filtration.
Historic use of mesh/suction filters has been proven to cause cavitation and premature pump failure.
Thus these typical suction strainers have to be made of very course mesh, rendering them unable to stop the damaging contaminants from entering the pumps and system.

Such is the problem with the historic use of these strainers that, this has seen Bosch Rexroth refuse warranties on systems using mesh suction filters.

But innovation has moved on, in conjunction with Magnom Corp, rexroth set out to test and understand the value of Magnom’s Magnetic Suction separator “The PumpMate”.

It will not be a surprise to hear that removal of ‘super hard’, ‘super sharp’ micronic particulate from systems can have a huge benefit for the systems.

Aggressive contaminants removed Pre-Pump

The Magnom PumpMate acheives this function:-

1, Pre Pump protection
2, To sub micron levels
3, Is non restrictive (no cavitation issues)
4, Is potentially fit for life (massive capacity so, no servicing required)
5, Flows as much fluid when full of contaminant, as when empty.
6, Low cost
7, No bigger than a suction strainer.

In testing carried out by REXROTH, the system fitted with the PumpMate hit “NAS 3” cleanliness,

The unit even removed some non ferrous contaminants (See analysis below).
So impressed were REXROTH, they committed to feature the PumpMate product on their stand at the Hanover Fair, in Germany.
PumpMate was also awarded the coverted REXROTH ‘AB’ standard for best practice product.

We know of no other filtration/separator that can be fitted to the suction side of a Pump without risk of invalidating warranty

Magnom & TEREX improving the performance of critical hydraulic and lubrication systems.

Following exhaustive testing, both in house and on live vehicle trials

TEREX have now adopted Magnom PumpMate products, as standard
Equipment on hydraulic systems.

This follows exhaustive evaluation of PumpMate product, fitted to the
suction ports of hydraulic pumps on their range of Dump Trucks.

Magnom PumpMate technology protects the pump and the entire system,
from recirculating wear materials, generated in the harsh conditions
in which the TEREX trucks are employed.

The PumpMate product can be a fit for life proposition, (fit and forget),
And can easily last the life of hydraulic systems, without requiring service.
(Note! system dependant).

Removal of ‘Super hard’, ‘Super sharp’ micronic contaminants from
these systems, (that are allowed to recirculate through conventional
Filtration), can have a massive positive impact on system life and health.

Thus increasing machine availability, increasing production, while reducing
maintenance cost.

A massive benefit to the machine/end user.

Magnom products are being widely used/specified by a wide range
of off highway OEM companies globally.
As well as many after market heavy equipment users
