Checkball Piston Pumps For Water-Based Fluids

Fined displacement checkball pumps are compatible with a variety of water-based and other low-lubricity fluids. Bi-directional shaft rotation provides constant direction of output flow regardless of drive shaft rotation.

MAINTENANCE-FREE DESIGN

The single-fluid checkball design uses the pumped fluid for internal bearing lubrication. This eliminates the potential for fluid cross-contamination, possible in other designs with isolated lubrication. It

TVPIUL APPLICATIONS

These pumps are ideal for use in wellhead safety control systems and other subsea applications, providing long life operating at high pressures with '.-.'ate;-based fluids.

They are also used on hydroform presses, and other applications rcquirmq pnvironniorr,.)lly (rmdly or fire-resistant fluids.

PUMP SELECTION

Thi-11 b U:' ^hows specifications for standard pressure models, and for high pressure ">-■'' option model! for maximum pressures to IS 000 psi (1040 bar). The "H" option requires high pressure coned and threaded or B.S.P. outlet ports. Refer to "Typical Model Code ' :o specify shaft, seal and outlet port options.
