MOUNTING

FLEXIBLE

RIGID

PIPE

The FLOJET G-57 Series self-priming pump should be

ounted in a dry and adequately ventilated area. This

m
pump can be mounted several feet from the tank, above
or below the fluid level. For most applications, no more
than 4 feet above the fluid level is recommended. This

is not a submersible pump.

Secure Dump to desired fixture by screws through the
rubber grommets in the baseplate of the pump. Ports
must be facing down. Contact factory for mounting
bracket and hardware options.

HOSE CONNECTIONS

Product In - Use 3/8”. 1/2” or 3/4”. reinforced hose or
equivalent. Avoid sharp bends that could restrict flow or
cause hose to collapse under vacuum.

Product Out - Use reinforced 3/8”. 1/2” or 3/4” I.D. hose
for discharge tube. 3/4” must use 90° elbows when
using large muffler.

Gas In - Make sure gas regulator is set at zero. Use
reinforced 1/4” hose. connect “Gas In” to gas supply
fitting on regulator. If pumps are installed in an enclosed
area, it is recommended to connect a hose to the gas
discharge port (exhaust) and vent gas to atmosphere.
(Requires ‘small’ exhaust port)

OPERATION

At start-up, regulate gas pressure to desired setting. For

ost installations 20 PSI (1.4 bar) inlet will be adequate,

m
although DO NOT go below 20 PSI. Pump will operate
according to air supply. Flow and pressure can be
adjusted by increasing or decreasing gas pressure to
accommodate varying product viscosities, length of

ines or other installation conditions. Review flow curves

l
located on page 1 for further assistance. High viscosity
fluids and hose length will limit priming distance.

IF PUMP IS T0 BE USED IN HIGH FLOW, LOW
PRESSURE APPLICATIONS, ADJUST GAS PRESSURE
TO 20 PSI (1.38 BAR) ABOVE DISCHARGE PRESSURE.

CAUTION: DO NOT EXCEED 100 PSI (6.9 bar) GAS INLET
PRESSURE.

CONTINUOUS OPERATION AT 120°F (48.9°C) WILL
REDUCE PUMP LIFE.

AIR MUST BE DRY AND OIL FREE.

Compressors must have dryers and/or a water
separator in the air distribution system. Pumps that fail
due to water in the air chamber will not be covered
under the limited warranty.

GENERAL SAFETY INFORMATION

Protect yourself and others by observing all safety
information. Follow all safety codes and the
Occupational Safety and Health Act (OSHA).

PLUMBING

Use a flexible hose to avoid excess stress on pump
ports. DO NOT crimp or kink hose. All hose should be
the same size as the pump port fittings.

All fittings must be compatible with fluid being pumped.
It is recommended to use plastic fittings only.

The use of check valves in the plumbing system could
interfer
unavoidable, check valves in the pumping system must
have a cracking pressure of 2 PSI or less.

Use a minimum 40 mesh strainer or filter in the tank or
pump inlet line to keep large foreign particles out of the
system.

PREVENTIVE MAINTENANCE TIPS

Tips to help pr

• If pumping liquid other than water. pump should be
flushed with water (if applicable) after every use.

Before freezing conditions occur. pump must be liquid free.

•

• If mounting pump in an outdoor environment. shield
pump from environmental extremes (i.e. sunlight.
water from washdown spray, rain, etc.).

• When using an air compressor. use an inline air dryer
before the pump to limit water build-up.

G57 DISASSEMBLY PROCEDURE

First, remove all gas (air in) lines and suction/discharge fittings
from me pump. This is accomplished by using a flat-bladed

ewdriver to slide the r

scr
and suction/discharge fittings and pulling the fittings away from
the pump body. Now remove the muffler by sliding the retaining
clip away from the muffler base and pulling the muffler out of the
pump body.

UsIng a Phillips screw driver remove the seven (7) screws from the
front end cap followed by the (7) screws from the rear end cap.
With the fr
on the workbench, position a flat bladed scr

ont end cap facing up and the r

Note the position of the suction and discharge valves before
removing them from the pump body. The first diaphragm is

emoved fr

r

om the pump shaft by unscrewing in a counter clock­wise direction. The second diaphragm is removed by placing the
flat tip of a screwdriver the exposed slot at the end of the pump
shaft and unscr

ewing me diaphragm fr
flange housing, place the tip of the flat bladed scr
air bleed hole on the lower side of the flange housing and lift up
the lower end separating the flange housing from the pump body.

The slide valve assembly and pump shaft can be removed by sim­ply pulling them from the pump body. The pump shaft then can be
removed from the slide valve yoke assembly.
