Checkball Piston Pumps For Water-Based Fluids
Fixed displacement checkball pumps are compatible with a variety ofwater-based and other low-lubricity fluids. Bi-directional shaft rotation provides constant direction ofoutputflow regardless ofdrive shaft rotation.
MAINTENANCE-FREE DESIGN
The single-fluid checkball design uses the pumped fluid for internal bearing lubrication. This eliminates the potential forfluid cross-contamination, possible in other designs with isolated lubrication. It also avoids the cost of a lubrication circuit.
RELIABLE HIGH PRESSURE
Individual piston checkvalves provide long service life and greatervolumetric efficiency, especially at high pressures and with low-lubricity fluids.
The checkvalvestake the place ofa valveplate in other pump designs. With no rotating sealing surface, checkball pumps are resistant to wearing and scoring.
TYPICALAPPLICATIONS
These pumps are ideal for use in wellhead safety control systems and other subsea applications, providing long life operating at high pressures with water-based fluids.
Theyare also used on hydroform presses, and other applications requiring environmentally-friendly orfire-resistant fluids.
PUMP SELECTION
The table shows specifications for standard pressure models, and for high pressure "H" option modelsfor maximum pressures to 10 000 psi (700 bar). The "H" option requires high pressure coned and threaded or B.S.P. outlet ports.
Referto "Typical Model Code" to specify shaft, seal and outlet port options.
