First 3:1 ratio high pressure diaphragm pump
First 3:1 ratio high pressure diaphragm pump
The Fluid Products Division of Ingersoll-Rand has announced the availability of what is claimed to be the first double-acting, 3:1 ratio diaphragm pump on the market. This new ARO highpressure pump can, it is claimed work with a wide range of applications and substances such as paint, high solids coatings, inks, adhesives, filled materials, drilling grout, caulking, solvents and resins. The new pump is also said to be ideal for use in systems where long pipe runs and consequent friction losses are unavoidable. As with all ARO diaphragm pumps, the new 3:1 ratio pump is covered by the company's no quibble five year warranty.
The new 3:1 ratio pump is the result of an intensive cross-engineering project, with the objective of producing a pump that incorporates the features of the ARO range of diaphragm pumps, yet produces high outlet pressures only available in the past from high cost, high-maintenance gear, rotary or other reciprocating-type pumps.
This pump also incorporates the exclusive ARO air valve design for stall-free operation, a standard operating feature of the ARO range of diaphragm pumps. With its 3:1 ratio design, the pump generates 21 bar (300 psi) of pressure from a standard 7 bar (100 psi) compressed air supply, offering enough pressure to work with any type of process fluid. The high developed pressure from a normal air supply also ensures that the pump can meet the requirements of long process applications with ease. The pump will deliver up to 90 litres/min (free flow) from 25 mm (1 in) fluid ports, providing enough material delivery to satisfy the most demanding application.
The pump is reported to be easy to maintain, with a bolted construction providing a more secure alternative to band clamp-type fasteners for an assured seal against leakage. The 3:1 ratio pump claims exceptional material compatibility in any environment with two body material choices between aluminum or passivated stainless steel.
Excellent compatibility is said to be offered by the durable internal stainless steel seats, checks and Teflon diaphragms. Critical fluid compatibility is also said to be possible even with abrasive and sheer sensitive materials. The sealless design eliminates the need for rotating or sliding fluid seals, avoiding it is claimed troublesome gland leakage associated with numerous pump designs.
