OILGEAR HIGH HORSEPOWER

TYPE "D" PUMPS

for service to

3500 P.S.I.

An extension of the well known Oilgear Type "D"

radial rolling piston, variable delivery pump line —

these pintle check type units do not compromise the

proven performance, reliability, flexibility and

adaptability of the established line. These units have

been laboratory and field operated under heavy duty

industrial conditions and proven themselves on di-

versified high pressure applications.

TYPE "D" UNITS ARE MORE THAN JUST-A-PUMP.

Like previous "D" pumps, these units incorporate a

positive, variable delivery, multiple radial rolling

piston high pressure pump . . . one or two controls

(selected from a wide variety) . . . high pressure

relief valves ... a gear pump with relief valve

. . . and an Oilgear pintle check type suction and

return valve for differential or non-differential two-

way systems (includes check, directional and relief

valves).

Using Oilgear two-way pumps, you can eliminate

many directional and flow control valves . . . simpli-

fy power and control circuits . . . save on piping,

fittings, electrical units and wiring . . . cushion

flow reversals . . . vary flow infinitely in either

direction.

These units are built in the same housing as pre-

viously built "D-15025" pumps and are dimensionally

interchangeable in most cases. If other system con-

siderations allow, they can replace existing units and

improve machine performance.

Detailed information on controls (see bulletin 47001)

and dimensional installations of pumps with controls

are published separately. Note, size 15030 and 15035

are available with the same controls as previous

"D-15025" pumps — the size 23030 is available with

type (A) air, (M) multi solenoid and (V) servovalve

controls.
