General Description
The MX44030PU-XXX fluid paint pump is designed for pumping High Viscosity
materials such as Mastic, PVC, Underseals, Sound deadeners and other similar
materials.
The fluid section is a ‘ROD’ type design which means the rod displaces the
material and is the only wear contact with the packings. A two-ball check valve
system ensures precise, smooth volume output. Tungsten Carbide ball seats
ensure maximum operating life between servicing.
The interior design maintains high flow capacity with minimum pressure drop
ensuring high efficiency; special surface treatments provide a smooth micro
surface making cleaning and flushing easier.
The piston and rod seals are the chevron type, which can be adjusted by means of
a gland nut, should wear occur, a preloaded wave spring is employed to adjust
and maintain the lower chevron packing preload when wear occurs. A built in
Solvent cup cleans and lubricates the pump rod and seals to prolong working life.
The air motor also utilises the Binks quick exhaust technology to prevent air valve
freezing conditions when high cycle speeds are employed.
The air motor is furnished with an exhaust muffler to control air exhaust noise
emission. An adapter kit is also available to facilitate connection to a piped
exhaust system if required.
Installation
This pump should be flushed with a suitable compatible solvent prior to use.
It is recommended that a propriety 1/2" BSP Filter / Regulator is used to provide
final control of the compressed air to the air motor.
Mount the pump securely and position the pump at a convenient height to allow
for maintenance, visual observation, and periodic inspection.
The Pump Assembly must be connected to a suitable earth ground to ensure that
there is no possibility of static build up.
Attach suitable pipework or flexible hoses designed to meet the working pressure
of the pump assembly (dependent on pump ratio) to the inlet and outlet
connections, e.g. 1½” Inlet and 1¼” Outlet.
Set the pump speed to a slow cycle rate and start the pump to remove any air
from the fluid circuit. Inspect for any air or fluid leaks.

Preventative Maintenance
Check daily to ensure that there is the correct type of lubricant material present in the solvent cup; this should
be compatible with the material being pumped. Confirmation from the material supplier should be sought to
ensure compatibility to prevent the risk of contamination.
Check daily for excessive material leaks into the solvent cup
A universal lubricant is available - Wet Sol ‘Plus’ Binks Part Number 863009

Fault Finding
Symptom Possible Cause Remedy
Motor will not run a. No Air supply
b. Air piston seal worn.
c. Pilot valve assemblies
inoperable.
d. Main air valve inoperable
e. QE valve defective
a. Check air and fluid supply ball valves and
supply hoses.
b. Replace Piston seal
c. Switch/interchange pilot valves to isolate
faulty pilot valve and clean/replace.
d. Check clean/replace Air valve.
e. Check for constant exhaust air when pump
is not in a stalled condition. Check/replace
QE cups
Pump runs but has
excessive pulsation
a. Worn piston seal.
b. Worn/failed shaft seals.
c. Damaged Exhaust Valve
d. Damaged Pilot Valve
e. Air exhaust restricted.
a. Replace seal
b. Replace shaft bearing / seal housing.
c. Inspect / clean and replace as required
d. Inspect / clean and replace as required
e. Inspect / clean and replace as required
Leak from rod seal
packings
Seal wear or damage to
packing material
Stop the pump and relieve all material
pressure. Tighten the gland nut until the
resistance of the packings clamping the shaft
can be felt. Do not over-tighten. Ensure solvent
cup has the correct lubricant for the material
being pumped present at all times.
Damaged rod Replace
Low material
flowrate, pump
running fast or will
not stall (stalling - 1
stroke should not
occur in less than 30
seconds)
Contaminates trapped
between ball and seat
Strip and clean pump.
Check for damage
Worn or damaged balls/seats Check for wear; replace balls and / or seats.
Worn bottom rod seals
Replace
