The model M160/P89 is the “Jumbo model” in the Arrow range of pumps. It is equipped with a very sturdy reciprocating pneumatic motor with a highly precise and reliable air reversing distribution system.
The flow capacity of the pump can be adjusted with considerable precision by adjusting the air supply using the ball valve.
This model is suitable for pumping medium to high viscosity fluids when required flows are up to 1900 l/h or for primarily output. It can be fitted with filters for chemical products since the pressure can reach up to approximately 24 bar (360 psi).
The P89 piston pump can be easily divided into two parts for cleaning; using a clean spare piston, the down time is reduced to only a few minutes.
(*) The flow capacities above are with water at 20°C, free flow opening and air supply at 6 bar.
The flow capacity depends on the viscosity of the product and the air supply pressure.
The pumping part is deliberately short so that the part immersed in the product is soiled as little as possible; it is therefore recommended to adjust immersion with it suspended on a lifting and lowering system using the eye bolt.
It is constructed mainly in stainless steel with parts in bronze and gaskets in high-quality virgin PTFE.
The upper part of the motor body is in special anti-corrosion aluminum and stainless steel.
