DiveMix offers Resato air-driven pumps that operate on the simple
but efficient principle of an automatic reciprocating differential area piston.
A relatively large air-operated piston (160mm for the P160 pump range and 200mm
for the P200 pump range) is connected to a smaller high-pressure piston to convert
compressed air flow into fluid flow at high pressure.
We have a complete range of single and double acting pumps. The single acting pumps
have one air piston and one high-pressure piston. The double acting pumps have one
air piston and two high-pressure pistons.
Because of the two pressure strokes, double acting pumps give a more continuous
flow and pressure. Compared with a single acting pump, a double acting pump has
almost half the air consumption for the same fluid flow. The air piston of the single
acting and double acting pump have the same diameter.
However, the diameter of the hydraulic piston varies and determines the ratio of
the pump: a higher ratio means a higher outlet pressure but a smaller flow. For
both single and double acting pumps we offer 10 different ratios for the P160range
and 9 different ratios for the P200 range. Thus, we can offer you a choice of 20
Resato P160 pumps and 18 Resato P200 pumps.
