The Model GP-6 is a hand-operated twin diaphragm Grout Pump.  It is designed to pump most types of water based grouts (not for epoxy type grouts).  This model features two separate pumps connected by common inlet and outlet manifolds.  Both pumps are powered by a single pump handle.


The pumping action of the pump is achieved by moving the pump handle back and forth (or up and down if the pump handle is in the optional horizontal position).  When the pump handle is moved to the right, the grout mixture in the hopper is drawn into the left pump, while at the same time the grout mixture already in the right pump is forced out into the placement hose where it is directed to the work area.  When the handle is moved to the left, grout is drawn into the right pump while the grout in the left pump is forced out.


1)  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.
2)  Move the vertical handle back and forth (or up and down if the pump handle is in the optional horizontal position) to draw the grout mixture from the hopper through the pump and out the clear placement hose to the work area.  CAUTION:  VERY MINIMAL PUMP PRESSURE IS REQUIRED TO FILL VOIDS WITH GROUT.  NEVER FORCE THE PUMP HANDLE.
3)  Be sure the work area is vented to allow any trapped air to escape.
4)  Do not allow the grout to harden while inside or on the outside of the pump or related components. Clean immediately after use.
5)  This pump is designed to be used with water based grouts only.  It is not to be used to pump chemical based epoxy grouts.


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 quality pre-packaged 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.
