GENERAL DESCRIPTION
The model 559X series chop-check grease pump is intended to be used
primarily for grease delivery systems. It uses carbon steel and other materials which make it compatible with most petroleum based lubrication
products.
NOTE: If this pump was purchased separately (not part of a system),
consult your sales representative for compatible dispensing accessories which will best match the application. All accessories must be able
to withstand the maximum pressure developed by the pump.

OPERATING AND SAFETY PRECAUTIONS
WARNING
plosion resulting in severe injury or death. Do not exceed maximum operating pressure of 517 bar (7500 p.s.i.) at 10.3 bar (150
p.s.i.) inlet air pressure. Do not run pump without using a regulator to limit air supply pressure to the pump.
WARNING
equipment failure resulting in severe injury or property damage. Do not exceed the maximum material pressure of any
component in the system.
Replacement warning label is available upon request, PN \ 94520.

PUMP RATIO X
Pump ratio is an expression of the relationship between the pump motor area and
the lower pump end area. EXAMPLE: When 10.3 bar (150 p.s.i.) inlet pressure is
supplied to the motor of a 50:1 ratio pump it will develop a maximum of 517 bar
(7500 p.s.i.) fluid pressure (at no flow) -- as the fluid control is opened, the flow rate
will increase as the motor cycle rate increases to keep up with the demand.

FLUID PRESSURE
NOTICE: Thermal expansion can occur when the fluid in the material lines is exposed to elevated temperatures. Example: Material
lines located in a non-insulated roof area can warm due to sunlight.
Install a pressure relief valve in the pumping system.

remove (46) guide unless replacement is necessary.
20. Remove (42) guide washer.
21. Clamp (37) lower suction tube horizontally in a vise. Unthread and
remove (31) extension tube and (32) gasket.
22. Using a 7/32” diameter rod inthe cross hole in (36) connector anda
9/16” wrench on the flats of (38) plunger, unthread and remove (36)
connector from (38) plunger. NOTE: Donot damage the o.d. of (38)
plunger in any way.
23. Using a 5/32” diameter rod in the cross hole of (41) primer rod and a
9/16” wrench on flats of (38) plunger, unthread and remove (41)
primer rod, releasing (40) ball and (39) ball stop.
prior to servicing.
3. Assemble(46) guide and (45) “U” cup into (47) valve body, securing
with (44) retaining ring. NOTE: Assemble chamfered corner of (46)

TROUBLE SHOOTING
If the pump will not cycle or will not deliver material.
• Becertain to check for non-pump problems including kinked, restric-
tive or plugged inlet / outlet hose or dispensing device. Depressurize
the pump system and clean out any obstructions in the inlet / outlet
material lines.
• Check all seals, including track gaskets.
• Check direction of “U” cup lips.
