This brochure contains specifications for the most commonly used checkball pumps. Contact the sales department for availability of models with features and operating requirements not shown here.Refer to page 28 for general fluid guidelines and information on ports. Request Bulletin PSI.CB (dynexpumprecommendations.pdf) for checkball pump installation and operating recommendations.
HOW THE PUMPS OPERATEThe checkball pump design uses two check valves in each piston pumping chamber to direct flow from the inlet side of the pump to the pump outlet port.
Wobble Plate Rotates with ShaftDuring operation, a fixed angle wobble plate rotates with the drive shaft. The angled surface of the wobble plate imparts a reciprocating motion to the pistons which move in and out of the bores in the stationary barrel.During its suction stroke, each piston is filled through its inlet check valve. Fluid is drawn by vacuum into the piston pumping chamber in the barrel.
Check Valves Control FluidDuring compression, the inlet check valve closes and pressure in the pumping chamber rises until it exceeds load pressure at the outlet port. The outlet checkball then lifts off its seat and fluid is pumped
across the check valve, out of the pumping chamber. Piston outputs are combined in the pump barrel or cover, and then discharged from the pump outlet providing smooth flow to the system.
Multiple Outlet PumpsIn Split-Flow® models, the piston outputs can be isolated, or grouped together in various combinations, supplying flows to multiple function circuits without flow dividers.

PUMP DESCRIPTIONFixed displacement checkball pumps, with bi-directional shaft rotation, provide constant direction of output flow regardless of the direction of drive shaft rotation.
Typical ApplicationsReduced power requirements, as low as 1.0 HP at 10 000 psi (0.7 kW at 700 bar), make these pumps ideal for use in remote locations with limited power supply. These compact high-pressure pumps can be used on portable power packs for high-pressure torque wrenches and other service tools. Split-Flow® models with multiple outlets are ideal for tool circuits with changing flow and pressure requirements.
MountingS.A.E. A-A 2-bolt pattern with 0.25 inch (6,4 mm) pilot engagement.
ShaftAvailable with 0.625 inch (15,88 mm) diameter keyed shaft.
Outlet Port OptionsStandard pressure models have S.A.E. ports.The high pressure “H” option requires the use of outlet port option “A” (Autoclave Medium Pressure, Butech M/P or equivalent fittings), or outlet port option “B” (British Standard Pipe fittings).
Inlet ConditionsPumps may require pressurized inlet conditions at higher speeds. Failure to meet minimum inlet requirements will result in a slight flow reduction. Refer to the table.
Seal OptionsStandard seals are Fluorocarbon (Viton® or Fluorel®). Options include EPR seals for
Output flow based on typical performance at rated pressure with pressurized inlet where required, as shown in the table below.
Contact the sales department for applications requiring continuous duty operation at speeds higher than 1800 rpm or lower than 900 rpm. See “Typical Performance Curves” on page 4.
➂ Higher than rated speeds may require a pressurized inlet. Refer to “Inlet Conditions”.
Values shown are based on fluid viscosity of 100 SUS (20 cSt). Inlet pressures higher than 10 psig (0,7 bar) require a high-pressure shaft seal. Refer to "Typical Model
Code" on page 6 for seal options.
use with some phosphate ester fluids, or Fluorocarbon with high pressure shaft seal.
Weight (Mass)11.9 lb (5,4 kg)
PUMP SELECTIONThe table shows specifications for standard pressure models and “H” option models for use at intermittent pressures higher than 8000 psi (560 bar). Ordering a PF500 Series pump requires a complete model code specifying shaft, seal and outlet port options. Refer to “Typical Model Code” on page 5.
Maximum PressureThe intermittent pressures listed in the table are the maximum pressures a pump can sustain for occasional, short periods of operation without appreciably reducing life expectancy.
Fluid GuidelinesSee page 28 for “Fluid Recommendations”.Some pump models may require reduced operating pressures when using low-lubricity fluids. Because of the wide range of fluid characteristics, contact the sales department for a review of any application using non-petroleum based fluids.
Split-Flow® Provides Multiple OutletsPF500 models with split-flow covers efficiently supply flows for multiple function circuits. Piston outputs are grouped together in the cover, with various piston flow splits available in this four-piston pump. Refer to “Typical Model Code” on page 5 and contact the sales department for availability.
Reduced Output OptionPump output can be reduced by one-half by deactivating two pistons. Refer to “Typical Model Code” on page 5.

PUMP DESCRIPTION
These fixed displacement checkball pumps are compatible with a variety of water-based fluids. Bi-directional shaft rotation provides constant direction of output flow regardless of the direction of drive shaft rotation.
Single-Fluid Lubrication DesignThe 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 also avoids the cost of a separate lubrication circuit.These pumps are ideal for use in wellhead safety control systems, other subsea applications, industrial equipment including hydroform presses, and other applications requiring fire-resistant fluids.

FLUID GUIDELINES
FLUID RECOMMENDATIONS
Mineral OilA high-grade premium petroleum-based fluid should be used to assure long component and system life. The fluid should have a combination of anti-wear, demulsibility, rust protection, oxidation-resistant and foam-resistant properties.
Special FluidsVarious pump models are available for use with water-based fluids, diesel calibration fluids, phosphate ester fluids, machining coolant, brake fluid, various military fluids and other special fluids.PF4300 Series pumps are compatible with a variety of water-based fluids. Refer to page 22 for specifications for these models, which are specifically rated for use with low-lubricity fluids. Some pump models may require reduced operating pressures when using low-lubricity fluids. Because of the wide range of fluid characteristics, contact the sales department for a review of any application using non-petroleum based fluids.
Viscosity SpecificationsUsing fluid with the correct viscosity range is critical to achieving long component life. Fluid conditions outside the “Optimum” range shown in the table may result in reduced pump output, requiring pressurized inlet conditions. For more information, contact the sales department.

➀ Fluid conditions outside the “Optimum” range may result in reduced output, requiring pressurized inlet conditions. Contact the sales department.
➁ Models with special mounting.
MINIMUM FILTRATION LEVELS
Pump inlet: 150 µ nominal;Pressure or return line: 25 µ nominal.While finer filtration levels than these are desirable and will result in longer component life, restricting flow to the pump inlet should be avoided. Minimum recommended inlet conditions must be maintained.If a system component fails resulting in fluid contamination, it is important to drain and clean the reservoir, all lines, filter screens and all components. Refill with new fluid.
INSTALLATION AND OPERATION
Refer to separate Bulletin PSI.CB for general installation and operating recommendations. That brochure includes information on mounting, shaft loading, sizing inlet pipe and hose, air bleed procedures and initial start-up. Guidelines for maintenance, repair and trouble-shooting are also included.
PORT DESCRIPTIONS
Dynex pumps are available with outlet ports suitable for use at various pressure ranges. Refer to the appropriate “Specification Table” or “Typical Model Code” to specify the required port.Contact the fitting manufacturer to ensure the selected fittings are rated for the maximum pump operating pressure.

The Straight Thread connection (S.A.E. J1926/1) is sometimes referred to as an S.A.E. O-ring Boss, or ORB. The port consists of a machined spotface surface, a tapered seal cavity and a straight thread port.The fitting forms a seal by compressing the o-ring in the seal cavity with the underside of the flanged wrench flat. Some adjustable fittings, such as elbows and tees, use a locknut with a captive backup washer for compression.S.A.E. Straight Thread ports are not recommended for operation above 8000 psi (560 bar). Also, the maximum pressure of pumps with No. 12 S.A.E. outlet ports may be limited by the pressure rating of the available fitting. Contact the fitting manufacturer for ratings.
High-pressure pumps are available with coned and threaded outlet ports, which use Autoclave Medium Pressure, Butech M/P, or equivalent fittings. These fittings provide a metal-to-metal seal with an interference fit, not requiring an o-ring. The gland nut holds the sleeve and tubing against the cone surface. A weep hole, visible on the outside of the pump cover, acts as an indicator of any abnormal leakage caused by system conditions (i.e., excessive pressure). It allows any fluid which does leak past the sealing surfaces to escape, preventing pressure build-up and possible damage.

High-pressure pumps are available with flat face ports with British Standard Pipe (B.S.P.) parallel threads (BS 2779 or ISO 228), ideal for use on some European applications.The fitting forms a seal by compressing a flat elastomer ring on a machined spotface surface. There are several sealing methods for these ports.
The recommended fitting has a recessed seal cavity formed by a shoulder on the underside of the flanged wrench flat (Voss “Peflex”, Form B Shoulder Seal; or Parker Type E, “EOlastic” Seal; or equivalent).B.S.P. ports are not recommended for operation above 10 000 psi (700 bar). Contact the fitting manufacturer, to ensure the selected fittings are rated for the maximum pump operating pressure.
S.A.E. 4-Bolt Flange Ports
Flange connections are often used for higher flows requiring larger diameter tubing. The port consists of an unthreaded port with four bolt holes in a rectangular pattern on a machined face around the port (S.A.E. J518).A typical fitting consists of a flanged head with a welded tube and a captive flange with bolt holes. A seal is formed by an o-ring in the groove on the underside mounting surface of the flange head. As the flange bolts are alternately tightened, the o-ring is compressed between the flange head and the machined face on the pump.To make mounting easier in tight spaces a two-piece split-flange is often used.
