GENERAL INFORMATION
The Model GP-3A is a air-operated single diaphragm Grout Pump.  It is designed to pump most types of water based grouts (not for epoxy type grouts).  It is made of long life durable materials, have an easy to replace diaphram and require minimal maintenance.  This pump works for grouting hollow metal door frames in place as well as placing grout anywhere that high pressure is not required.

 

DESCRIPTION
A pneumatic cylinder is used to move the diaphragm up and down. When the cylinder retracts, the diaphragm draws the grout mixture through the open intake flapper valve into the pump.  When the cylinder extends, the grout movement causes the intake flapper valve to close while opening the outlet flapper valvel.  This forces the grout mixture from the pump into the placement hose where it is directed to the work area.

 

APPLICATIONS
Filling hollow concrete block walls.
Grouting metal door & window frames in place.
Hollow areas under machine bed plates.
Filling voids.
Placing grout anywhere that high pressure is not required.

 

OPERATING INSTRUCTIONS
1)  Some grouts are more difficult (or impossible) to pump than others.
2)  Check that the "ball valve" (yellow oval handle) and the "stop/start switch" (brass switch on top of cylinder) are both turned to "off" position.
3)  Attach an air source from your compressor to the "ball valve".

4)  The "pressure control" is the yelow round knob.  Turn clockwise to increase pressure, counterclockwise to decrease pressure.  Normal operating pressure is 30 psi.  Never adjust pressure above 50 psi to avoid damage to pump.  As a reference, grout line pressure is approximately 1/3rd of what is shown on the air gauge (i.e. 30 psi on gauge would indicate 10 psi grout line pressure).  If air pressure is adjusted below 20 psi, pump will not cycle.
5)  The "speed control" is a black knob with a red ring.  Turning it clockwise will slow the cycle speed, counterclockwise speeds the cycle speed.  It is a good idea to start the pump slowly, then increase the cycle speed after the grout has started to flow from the end of the placement hose.

6)  With the air supply hose connected abd the "ball valve" turned on, the pump can then be started and stopped from the "stop/start" switch on top of the air cylinder.
7)  Place grout in a suitable container and mix per manufacturers recomendations.  Pour mixed grout mixture into hopper.  Some grouts, such as Fosroc Renderoc LA, require that the pump be primed with a cement/water slurry.
8)  Start pump using the "start/stop" switch.  Adjust pressure and speed controls as required. CAUTION:  VERY MINIMAL PUMP PRESSURE IS REQUIRED TO FILL VOIDS WITH GROUT.
9)  Be sure the work area is vented to allow any trapped air to escape.
10)  Do not allow the grout to harden while inside or on the outside of the pump or related components. Clean immediately after use.
11)  This pump is designed to be used with water based grouts only.  It is not to be used to pump chemical based epoxy grouts.

12)  When servicing the pump, be sure to remove the air supply hose and turn off the "ball valve" to depressurize the system.

 

PERFORMANCE RECOMMENDATIONS
1)  Always use the shortest length of placement hose as possible.  The ideal length is five feet long. When grouting door frames, place the pump on a cart or platform to allow use of the standard five foot long placement hose.
2)  Always use the largest diameter hose that access will allow.  The ideal size is 1-1/2" inside diameter.  Never use a "rubber based" hose.
3)  It is always recommended that a good quality pre-packaged non-shrink grout be used.  These products usually contain additives that allow the grout to flow easier.
4)  If you are mixing your own grout (sand/cement/water) mixture, the mix will require additional cement in order to keep the sand in suspension.  When pumping "home made" grout, extra time will be required to find the exact proportions to achieve a pumping mixture.  Adding a plasticizer to the mixture will be benificial.
