Maintenance
8.1
Changing fluid types
Changing between mineral based fluid types and phosphate
ester-based fluid types is prohibited. The two configurations
of this pump are not compatible with each other. Only use the
fluid for which the pump is designated.
8.2
Hose
The corrugated hose should be checked before each use and
replaced on-condition. Any of the following discrepancies are
cause for replacement of the hose:
1.
Brittleness / cracking
2.
Severe mechanical damage
3.
Leaks / seeps
4.
Bulges
5.
Burns
6.
Bubbling / melting of the outer corrugated protective
cover
7.
Use of incompatible fluid
8.3
Filter
The tank filter is a non-bypass design. Longer than normal
service time and / or slower than normal flow is an indication
of a filter that needs cleaning / replacement. This can be
verified by timing the flow into a container. For example, a
new 2 micron filter will fill a 500ml bottle in 10 seconds at
operating pressure with a 5 psi pressure loss out of the pump
outlet. If a significant reduction in flow is noted, perform
the following cleaning procedure:
1.
Use appropriate personal protective equipment.
2.
Purge the oil from the tank and lines into a suitable
container through the discharge nipple.
3.
Remove the filter assembly from the system JIC supply
line and MNPT fittings on the valve block
4.
Cleaning 2 micron filter (welded stainless steel):
a.
Remove rough external dirt in a separate container
by soaking the filter for thirty minutes in a high
quality cleaning fluid.
b.
Blow through the element from outlet to inlet
(reference arrow mark) with clean 20-30psi of
compressed air or similar clean gas.
c.
Remove any remaining water particles by dipping
the filter in isopropyl alcohol then allowing it
to dry.
