Hydraulic Triplex Pumps

At theHeart of Industry



Kobe Triplex Pumps are extremely dependable, heavy-

duty pumps designed to serve as high pressure sources

of hydraulic power for many types of hydraulic systems.

They are particularly adapted for severe service involv-

ing frequent hydraulic shocks in the system, high

temperatures, and a variety of hydraulic fluids. They are

plunger type pumps for pressures up to 30,000 psi and

for displacements up to 200 gpm.

There are three basic sizes (Size 2, Size 3 and Size 4)

with several modifications available for each. All Kobe

Triplex Pumps include vertical design, automotive type

crankcase, spring-loaded ball type valves with replace-

able seats or disc-type valves, a built-in lubricating oil

pump for dual pressure and splash lubrication, an

optional scavenging pump to return plunger leakage to

the system, and built-in reduction gears. Units are

available with integral motor drive or with external drive

shaft for separate coupling drive.

Chrome-plated steel plungers, lap fitted to liners

centrifugally cast of high-grade alloy iron, are available

with a variety of cylinder blocks to accommodate

pressures above 5,000 psi. Packing is available for other

applications where needed. Plungers and liners areinterchangeable, as assemblies, to meet a wide range

of pressure and volume requirements. The Kobe Triplex

is a complete, self-contained unit and the most com-

pact high pressure triplex pump on the market today.

“KOBE TRIPLEX PUMPSreally stand up under pressure”

Easily installed and maintainedInstalling a Kobe Pump is a breeze. There are no align-

ment problems. No special mounting base is necessary

– four hold-down bolts are sufficient. Compactness

saves valuable floor space. One man can easily service

the unit and replacements are no problem. The tall

spacer block provides large, unobstructed hand-hole

openings. Plungers and liners may be changed quickly

and easily.

Maximum safety The Kobe Triplex has no exposed moving parts, no

gears, plungers, or tie-rods requiring screens or guard

rails. Most units have a built-in relief valve to prevent

over-pressuring the system.

Integral electric drive is optionalKobe Triplex Pumps are available with an integral motor

drive, or with a stub shaft for separate drive. Standard

motors are 230/460 volt, three phase, induction type,

operating at 1800 rpm. Variations are available upon

request.

Horizontal mounting availableThe Kobe Triplex is a vertical design but for special

applications is available in a horizontal mounted

position.

VALVES – ball type with

seated in a taper, have inside

threads for easy removal.

INTEGRAL ELECTRIC

MOTOR – is optional.

Motors are 230/460 volt,

60 Hz, induction type.

LUBRICATION – built-in lube

oil pump supplies oil under

pressure to crosshead

guides and connecting rod

bushing. Excess oil is

delivered to the reduction

gears. Splash lubrication is

within the crankcase.

INTEGRAL

REDUCTION GEARS –

precision cut and

hardened; provide

double reduction.

SCAVENGER PUMP

(optional) – disposes

of plunger drippage

in the spacer block

through an external

tube connected to

the scavenger pump.

PLUNGERS AND LINERS –

metal to metal, lapped fit –

no packing required. Packedplunger and liners are available for

fluids being pumped at pressures

below 5,000 psi. Liners are

secured in the cylinder block by a

4-bolt flange, and are quickly and

easily removed. Plungers are free-

floating in the plunger connector.

A wide range of pressures and

volumes can be achieved by

changing plunger and liner sizes.

CYLINDER BLOCK – machined

from a heavy one-piece steel

forging. Standard blocks are

rated to 5,000 psi; other blocks

for Size 3 Units to 20,000 psi,

and Size 2 Units to 20,000 psi.

SPACER BLOCK –Tall and unobstructed; easy

access to plungers and liners.

Design minimizes heat transfer

from cylinder block to crankcase

in high temperature applications.

Fluid is completely enclosed

within the spacer block

preventing leakage beyond

the pump.



SIZE 2 Triplex Pump

The Size 2 Triplex Pump isused throughout steel rollingmills for high pressure bearing lubrication and

general hydraulics.

The 5,000 psi cylinder block in the standard Size 2

product line accommodates interchangeable

plungers and liners of nine different sizes. The

20,000 psi block handles six different plunger and

liner sizes and is limited to lubricating fluid service

only. The 30,000 psi version has three valve

cylinders (rather than

the forged cylinder

block) and has four

sizes of interchange-

able plungers and

liners. Inlet and outlet

connections are at the

same end of the

cylinder block.

Integral motor types

available are drip-

proof, TEFC, or

explosion-proof, and

are 230/460 volts, 3

phase, 60 Hz, 1800

RPM. Speed reduction

gear ratios availableare 3.986 or 5.204.

The 5,000 psi

version of this unit

can be obtained with

modifications which

make it capable of

handling straight

water, high tempera-

ture fluids, or other

special services.

The displacement

figures on the nextpage are in GPM and

the pressures in psi.

*Inlet and discharge connections will vary in size and will

be determined by pressure rating and fluid end design.

FLUID END DESIGNS ...

This basic design is utilized to 10,000 psi

in most applications. Valving is springloaded ball-type and seats are tapered

inserts. Plunger and liner design is metal-to-

metal with a close clearance to provide

dynamic seal. For fluids near ambient

temperature, an “O” ring is utilized as a

secondary seal. Cylinder block typically

is alloy steel forging.

STANDARD• Light Hydrocarbons

• High Temperatures

• Water with Oil

• Oil

WATER • Semi-corrosive Fluids

• Potable Water

• Brackish Water

• Process Fluids

This design is utilized to 5,000 psi in

most applications. For higher pressures,the design is similar to the 30,000 psi

version. Stainless steel valving is spring

loaded disc-type and seats are tapered

inserts. Plunger and liner assemblies are

self-adjusting for packing wear. Plunger

and liner assemblies are easily installed

and removed so that re-packing may be

done on a bench. Cylinder block is

alloy steel for most applications.

Shown here are some of the fluid end designs available for a wide range of services offered

in the Kobe triplex pumps. All are characterized by unique features and all offer exceptional

dependability and simplicity of maintenance.

• Liquid Ethylene

• Liquid Hydrogen

• Liquid Carbon Dioxide

30,000 PSI• Oils

• Water with Oil

• Light Hydrocarbon

• Water (to 15,000 psi)

This design is utilized for most cryo-

genic fluids in pressures to 6,000 psi.For higher pressures, the design is

similar to the 30,000 psi version.

Jacketed stainless steel cylinder block

provides a means of immersing the

fluid end in the fluid being pumped.

Stainless valving is spring loaded disc-

type and seats are tapered inserts. In

the plunger and liner assembly there are

a series of sealing elements consisting

of Teflon rings with stainless steel

contracting rings.

For higher pressures, the Kobe fluid end

consists of three valve cylinders withexternal inlet and discharge manifolds.

Valving is stainless steel, disc-type and

in tandem arrangement. All sections of

the stainless steel valve cylinder subject

to stress are circular and free of inter-

secting holes. As with other fluid ends,

the plunger and liner assemblies are

flange retained and easily

interchangeable.

In each case, the illustration represents the complete fluid end which is bolted to the spacer block.

The button at the bottom of the plunger has a floating connection to the crosshead stem.
