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 Design

The 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.

Mounting

S.A.E. D 4-bolt pattern with 0.25 inch

(6,4 mm) pilot engagement.

Shaft Options

Standard keyed shaft, 1.250 inch

(31,75 mm) diameter;

Optional spline shaft, 1.248/1.247 inch

diameter standard S.A.E. 14 tooth,

/24 D.P. 30° involute spline.

Outlet Port Options

Standard pressure models have S.A.E. ports.

High pressure “H” option models require

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 Conditions

Pumps may require pressurized inlet

conditions at higher speeds. Failure to meet

PUMP SELECTION

The table shows specifications for standard

pressure and high pressure “H” option models.

Refer to “Typical Model Code” on page 25 to

specify shaft and outlet port options.

Maximum Pressure

The maximum pressures listed are the

highest pressures a pump can sustain for

occasional, short periods of operation without

appreciably reducing life expectancy.

Special Fluid Operation

Because of the wide range of water-based

fluid characteristics, contact the sales

department for a review of any application

using non-petroleum based fluids.
