Cat Pumps introduces new triplex plunger pump

Cat Pumps, a manufacturer of high pressure triplex positive displacement plunger pumps, has extended its 35-frame series with the introduction of the Model 3550. Delivering pressures up to 414 bar (6,000psi) and flows of 38l/min (10gpm), the new pump is ideally suited to operating in high-duty cycle applications in remote locations of where a mobile unit is required.

Cat Pumps model 3550 has been developed for demanding applications requiring long-life and dependable performance. Available in direct drive and belt drive options, applications highlighted by Cat Pumps include hydrostatic and destruct testing, water jetting, high pressure tooling, water blasting, high pressure injection and surface preparation.

Using advanced engineering design software, Cat Pumps has optimised every detail to produce a pump offering extended, trouble-free service life. Key features that deliver optimum operation include concentric, high density polished solid plungers for long seal life, V-packings and low pressure seals that are fully lubricated and cooled. Also contributing to longer service operation are the drive end matched connecting rods and oversized bearings which accommodate greater loading capacity, whilst hard chrome-plated forged brass inlet/discharge block manifolds offer enhanced strength and fluid compatibility. Maintenance is simple as servicing the wet end is undertaken without having to enter the crankcase.
