INSTALLATION
MOUNTING PUMP
Mount pump to suit the type of installation planned.
Mounting accessories are available through your
local distributor.
This is a sanitary shovel pump. The pump is
designed to mount on a 55 gallon or 5 gallon ram
with a ram plate attached to the foot valve of the
pump. The warnings regarding MOVING PARTS
HAZARD on page 2 should be paid close attention.
Screw the air exhaust muffler (A) into the 3/4” NPT
outlet (B) in the air motor base. See the TYPICAL
INSTALLATION. If lubricants, air line scale, rust,
etc. could contaminate material, plumb exhaust air
outside of the fluid product zone.
Ground the Pump and System
Read the warning section FIRE OR EXPLOSION
HAZARD on page 3 and ground the pump and
system as explained there.
CONNECT THE HOSES
Install an accessory air filter-regulator assembly
(C), lubricator (D) and solenoid valve (E) in the
pumps 3/8” NPT air inlet (F) as shown in the
TYPICAL INSTALLATION. See page 10 for the
recommended air filter-regulator and lubricator.
Connect a 0.5” (13 mm) ID air supply hose to the
1/2” NPT inlet of the filter regulator (C). The main
air supply must include a bleed type master air
valve (G), required, for shutting off and relieving
air pressure that may be trapped between the
valve and air motor and cause it to cycle
unexpectedly.
Connect a fluid hose to the pump’s flanged outlet
(H). See the accessory sanitary hose fittings kit on
page 10.
Installation of the complete system should be in
accordance with all state sanitary codes and/or
local requirements.
Connect air solenoid valves (E) to actuating
mechanism (timer) and set so the automatic valve
(J) will dispense at proper intervals.
OPERATION
NOTE: If necessary, flush the pump with an
approved cleaning solution or disassemble and
sanitize the parts before using the pump. Refer
to the CLEANING PROCEDURE. Check local
and state codes for specific limitations.
Adjusting the Pump Speed and Pressure
WARNING
Never allow the air pressure to the pump to
exceed 120 PSI (8.4 bar). Higher pressures will
cause the pump to exceed its maximum
recommended sale operating pressure of 600
PSI (42 bar).
Before turning on the air to start the pump, fill the
lubricator bowl to the level mark with a
phosphate/ester-free SAE 10 machine oil.
With the air supply turned on, the pump starts
when the automatic dispensing valve is opened,
and stalls against pressure when the automatic
dispensing valve is closed. In a circulating system,
the pump operates until the air supply is turned off.
Always use the lowest air pressure needed to give
the desired results.
Lubrication and Care of the Pump
Do not subject the air motor to temperatures higher
than 200°F (93°C), and the immersion fluid pump
to temperatures higher that 200°F (93°C).
Excessive temperatures may damage the pump
packings and seals.
If the pump accelerates quickly, or is running too
fast, stop the pump immediately and check the
fluid supply. If the fluid supply is empty and air has
gotten in to the system, re-primer the pump and
lines with material, or flush and clean the pump
and the system. Always stop the pump at the
bottom of its stroke to prevent material from drying
on the displacement rod (the air motor exhausts at
the bottom of the stroke).
