PGP 35-5 Portable Grout pump
The PGP35-5 grout pump, double acting motor air-driven, allows the grouting under pressure of different fluids like water, cement slurry or bentonite. It operates on the simple but efficient principle of an automatic reciprocating differential area piston. A relatively large air-operated piston is connected to a smaller high-pressure piston to convert compressed air flow into fluid flow at high pressure.
The standard ratio of 5 multiplies by the air inlet pressure gives an output pressure up to 500 psi (35 bar)*.
Its reduced weight and size make it very suitable for narrow space worksite avoiding heavy equipment.
(*) The option PGP70-10 pump is available under request : 1000psi ( 70 bar ) , 6 gallons (35 liters) per minute.
