OILMASTER 5:1 OIL PUMPS
T512-01(Aluminium) T512-01-11 (Zinc)
INSTRUCTION MANUAL
INTRODUCTION
Thank you for purchasing a Macnaught air
operated oil pump. The Macnaught T512 Oilmaster is a
5:1 ratio, double action piston type stubby pump
designed to dispense lubricating oils (eg: engine oils,
hydraulic and gear oils) from bulk tanks or drums
through pipelines, hose reels and hose end oil delivery
guns with or without a flow meter.
The Oilmaster is supplied with a standard 2” BSP
adjustable bung adaptor which is suitable for most tanks
and drums. The fluid inlet of the pump is tapped 1” BSP
female (or 1” NPT for USA/Canada) so you have the choice
of either supplying your own threaded suction tube or you
can purchase the optional Macnaught telescopic
suction tube kit (TB25s) which is suitable for drums or
tanks up to 1.2 metres (48”) deep.
Macnaught manufacture a full range of accessories to
suit the T512 Oilmaster, please consult your local
Macnaught reseller for more information.
With your appropriate care combined with the Macnaught
Guarantee of dependable after sales service, provided
by our worldwide distribution network, you will be assured
of continuous safe, efficient and reliable product
operation
Please read and retain this instruction manual to assist
you in the operation and maintenance of this quality
product.
GENERAL INFORMATION
This manual assists you in operating and maintaining
your new T512 Oilmaster. The information contained will
help you ensure many years of dependable performance
and trouble free operation.
Please take a few moments to read through this manual
before installing and operating your T512 Oilmaster
pump. If you experience problems with the product, refer
to the Maintenance and Trouble Shooting sections of this
manual. If you require further assistance please contact
your local Macnaught Distributor, Authorised Macnaught
Service Centre or Macnaught.
IMPORTANT INFORMATION
Read this information carefully before use!
Your safety is important to us. Please read, understand
and follow all safety instructions listed below. Some of
these instructions alert you to the potential for personal
injury. ‘Cautions’ listed throughout the manual advise
of potential practices or procedures which may cause
damage to your equipment.
Make sure all operators have access to adequate
instructions about safe operating and maintenance
procedures.
Do not exceed the maximum recommended air-inlet
pressure of 1035 kPa/ 150 psi/ 10.3 bar. The pump
requires a minimum air inlet pressure of 400 kPa/ 60
psi /4 bar and we recommend that you operate the unit
at 690 kPa/ 100 psi/ 6.9 bar.
Do not hit unit if it fails to operate. Refer to ‘Trouble
Shooting Guide, or return unit to your nearest
Authorised Service Centre.
Use suitable thread sealant (eg Teflon tape) on all
screwed fittings, but do not over tighten to avoid
component damage.
This pump has been fitted with a pressure release
valve. This unique feature will protect both the pump
and the system against damage created by excessive
pressure, possibly caused by thermal expansion.
Never allow any part of the human body to come
in front of or in direct contact with a material
outlet. Never point the nozzle of the gun at yourself or
anyone else.
Most accidents occur because of a component
rupture. Be certain that any and all system
components will withstand the pressures being
developed. Never exceed the pressure rating of any
component installed in the system.
Weak, worn or damaged hoses are also a hazard.
Before each use check hose for signs of wear, leaks or
loose fittings. Tighten all fluid connections regularly
and replace weak or damaged hose. Your personal
safety and well being are at stake.
WARNING
Before attempting any repairs or maintenance of this
product disconnect air supply and release oil line
pressure by squeezing hand piece/gun trigger.
ASSEMBLY
1) Measure the depth of the drum/tank and attach
appropriate length of 1” BSP (1” NPT USA/Canada)
threaded pipe to the inlet of the pump (or use a
Macnaught suction tube kit TB25s).
2) Remove the bung adaptor assembly from the pump
and screw into drum/tank opening. Carefully lower
the pump through bung adaptor and tighten the clamp
screw located at the clamp sleeve.
Note: There is a wire mesh strainer located in the brass
air inlet. It is recommended that a micro-fine (5 micron)
in-line air filter is fitted to the air inlet to ensure maximum
efficiency of this pump.
3) Before connecting the air supply, the user should add
a ‘stop’ compressed air cock.
Note: The air cock must be a ¼ turn type (allowing quick
closure ) and should be located close to the body of the
pump and be easily recognised.
OPERATION
1)
Ensure that the drum or tank is ‘vented’.
2)
Partially open the on/off air valve.
prime automatically.
3)
Open the oil delivery outlet/nozzle. The pump will
automatically start.
4)
Adjust on/off air valve to regulate the flow. Close
delivery outlet/nozzle to stop flow.
The pump will
Caution! Do not run the pump dry. Remember to switch
air supply off if not using the pump for an extended period
e.g. at the end of each working day.
MAINTENANCE
Before carrying out any maintenance disconnect the air
supply and release the fluid pressure in the system.
Inspect your oil pump weekly for any signs of damage.
Replace any suspect or damaged parts/components as
required.
Every 2 weeks (or sooner if the pump is used every day)
apply a few drops of light oil to the air inlet of the pump.
(Sewing machine oil is ideal).
PUMP DISASSEMBLY
1) Remove oil hose from the pump unit.
2) Withdraw pump from the oil drum/tank. Use a clean
bench to carry out maintenance.
3) Remove the 4 screws (19) holding cylinder (7) to base
(14). Lever the cylinder off the base. There is a slot in
the base near the valve body (31).
4) Remove the cover screw (6) and valve body cover
(33).
5) Remove the 6 screws (35) holding the valve body (31)
to the cylinder (7). Remove the valve body assembly
and valve gasket (29).
6) Pull out the 2 brass pins (34) from the valve body.
Lever out the valve plugs (30) and (39).
7) Gently push the spool (36) out of the valve body. Be
careful when removing the O-Rings (5) and (38).
8) Remove top (long) poppet valve assembly (2), (3), (4)
and O-Rings (1), (5) and the bottom (short) poppet
valve assembly (28), (32) (3) and O’Rings (1) (5).
9) Hold hex section foot valve (27) horizontally in a vice.
Hold air piston firmly and unscrew allen head screw
(8). Remove screw and piston from piston rod.
10) Carefully unscrew the foot valve and pump cylinder
assembly (24), (25), (26) (27) from cylinder base
(14).
11) Withdraw the piston and piston road assembly from
the cylinder base.
12) Clean and inspect all parts. Replace any suspect or
worn or damaged parts.
PUMP REASSEMBLY
1) Ensure that all parts have the correct orientation. If
parts are assembled upside down, the pump will not
work. Check the parts diagram for correct orientation.
2) Apply thread sealant (Loctite or similar) to pump
cylinder thread (24) when reassembling the unit.
3) Assembly of the pump is a reversal of the disassembly
procedure.
4) Ensure that all O-Rings, particular in the valve body
(31) and poppet valve (2), (28) areas sit square.
5) Apply light grease (eg Petroleum Jelly) to O-Rings (17),
(43) and piston seals (11) before fitting cylinder (7) to
base (14).
6) Fit the pump to your oil drum/tank and reconnect
the oil hose and air supply. Open dispensing nozzle
to ensure correct operation.
