Cat Pumps has extended its flushed positive displacement triplex plunger pump range with the introduction of the 661CModel. Flushed triplex plunger pumps greatly enhance seal life and keep maintenance costs down when pumping low lubricity and high temperature liquids.

Capable of delivering flows of up to 38l/m and pressures up to 210 bar the 661C 15 frame plunger pump features a special ported inlet manifold that permits a lubricating barrier liquid between the high and low pressure seals and also helps to cool the seals. This flushing liquid is not returned to the pump inlet port, but is re-circulated to the external flushing supply creating a managed system. This external flush provides cooling when pumping high temperature liquids and added lubrication when low lubricity liquids have to be accommodated. The stainless steel liquid-end offers compatibility with a variety of liquids.

The flushing liquid dilutes and flushes away any seepage past the high pressure seal and prevents crystallization from fluids containing high concentrations of dissolved solids. The containment feature offered by this sealing system brings two additional key benefits:

Where hazardous fluids are being pumped, seepage can be disposed of safely.
Monitoring of the contained fluid provides an early warning of seal wear.

Being a triplex plunger design, the SS 661C gives a constant smooth flow making it ideally suited to a wide range of industrial processing duties and is ideal when applications involve pumping:

Ultrapure water
Chemicals
High-temperature liquids
Environmentally unfriendly liquids

Having the capability to handle low lubricity fluids, such as ultrapure water, makes the pump ideally suited for applications in the high precision industrial electronics industries.

In keeping with Cat Pumps’ quality commitment, the 661 has been designed and constructed for optimum operating life and easy maintenance. The high strength connecting rods and plunger rods, together with oversized crankshaft bearings give a greater load capacity and longer drive-end and bearing life.
