Applications, Accessories and
Principal Operation
The HEYPAC is a double acting, free piston,
compressed air driven hydraulic pump of infinitely
variable delivery for general use wherever a
compressed air supply is available. The pump will
cycle automatically according to system demand
and stall under zero flow conditions with minimal
energy consumption. The output flow and
pressure depend upon the intensification ratio
relative to the air supply pressure and volume.
The air operated fluid pumps and hydraulic power
packs are currently available with fluid-to-air
pressure ratios from 2.5:1 to 80:1. All models
employ similar air drives with only the fluid end
varying in size to produce the different pressure
intensification ratios. Key areas of the pumps
construction and operation are described below.
AIR VALVE - a self reciprocating valve that
alternates the compressed air supply to the upper
and lower sides of the drive piston assembly
generating the pumping motion of the unit. A
unique system of pilot control produces positive
spool reversal.
AIR DRIVE - a lightweight drive piston complete
with self lubricating seals allows the pump to
operate on an unlubricated air supply.
PISTON ROD - transmits the compressed air power
to the fluid being pumped.
The cross sectional area of this piston in relation to
the air drive piston provides the pump
intensification ratio.
TRANSFER VALVE - is closed as the piston rises,
B via
drawing fluid into the lower pump chamber A
the suction valve and at the same time the piston
A to the
displaces fluid from the upper chamber A
system. When the pump reverses and the piston rod
begins to fall the suction valve is closed by the
increase in pressure in the lower chamber and the
transfer valve is opened. Fluid is then displaced
through the transfer valve to the upper chamber
where the excess fluid is again forced into the
system.
A
B
2"
SUCTION VALVE - opens to allow fluid to enter the
pump as the piston assembly rises.

Installation Considerations
The HEYPAC GX and KR series
pumps are rugged and high
quality products and their long
service life can be increased by
correct installation.
Filtration
Suction strainers (125 or 40 micron
depending on model) are supplied
in all units fitted with a reservoir
but not included with 00, T and W
configuration pumps.
Additional system filtration to 25
micron or better is recommended.
An extended suction tube kit,
complete with suction strainer, can
be supplied for T configuration
pumps that are to be tank
mounted.
Fluids
The pumps will handle a wide range of fluids including those
with little or no lubricating properties.
Air supply - an auto drain
filter/regulator (25 micron) should
be fitted as close as possible to the
air inlet and be of sufficient size
for the air consumption
anticipated. The air drives of the
pumps are greased on assembly
and therefore should not be used
on lubricated air supplies as this
will wash out the grease and
shorten service life.
Fluids which have been satisfactorily pumped include:
Mineral Oils
Vegetable Oils
High water-based fluids
Water Glycol solutions
Water in Oil emulsions
Phosphate Esters
Silicate Esters
Grease
Liquified Gases
Water (For applications involving water, the option W should be
inserted in the pump model number).
Valves and Sytem Components
Due to HEYPAC's ability to maintain pressure at zero flow,
consideration should be given to fitting ultra low or no leakage
valves, such as poppet construction, and by so doing, the pump
will be protected from excessive cycling. A range of suitable
valves are available.
Mounting Orientation
Pumps can be mounted in any orientation with the exception
of all R configuration pumps. The R1, R2 and R5 models must
be mounted vertically with the reservoir beneath the pump
while the R3 and R4 models should be mounted horizontally.
2"
Flow Control
A suitable flow control must be used if the pump is to be
operated at or near maximum flow rate to prevent
overspeeding.

Accessories & Custom Solutions
Reservoir Kits
In addition to the integral R series of reservoirs
HEYPAC is able to offer larger reservoirs with 10 or
30 litre usable capacity suitable for mounting T1 or
T2 option pumps.
The reservoirs are epoxy powder - coated inside
and out and are supplied complete with fluid level
gauge, air breather/filler and pump suction tube
and strainer.
The 30 litre reservoir includes a return line filter as
standard, which is an optional extra on the 10 litre
reservoir. The 10 litre reservoir will accept a single
GX or KR series pump and the 30 litre reservoir will
accept single or twin pump installation from either
GX or KR series or a mix of both series.
A fluid level switch is an optional extra on either
size of reservoir. Larger capacity reservoirs are
available on request.
Manifold Options
The GX and KR series of pumps are available with
an integral manifold conforming to ISO standards
to enable the direct mounting of control valves.
The GX20 to GX80 and KR05 to KR40 pumps can be
supplied fitted with a manifold conforming to
ISO 4401-03-02-0-94 and the KR05 to KR40 pumps
can also be fitted with a manifold conforming to
ISO 4401-02-01-94.
The manifolds are available with both BSP and SAE
(UNF) service port threads.
System Accessories
Smoothing Kits to suppress the slight pressure
pulsations generated by the reciprocating pump
mechanism when perfectly smooth flow is required.
Fluid Level Switches for use with R1, R2, R5, 10
and 30 litre reservoirs to warn of low fluid level,
supplied complete with DIN connector.

Return Line Filters 20 micron nominal rated for
use with GX20, 30 and 40 pumps when fitted to R1,

Valves
A wide range of directional control and pressure reducing
valves are available to suit all air driven pumps. The valves
have been selected for their no or ultra-low leakage
characteristics and are typically of poppet construction.
Directional Control Valves are available in 3 or 4 port
configurations for the control of single or double acting
cylinders or other diverting functions. The range of valve
operators include direct solenoid, in most popular voltages
and also an EEx rated option for explosive environments,
air pilot and lever operated. The valve mountings conform
to ISO 4401-03-02-0-94 and therefore the valve may be
directly fitted to all pumps with options M or M3 or on to
manifolds conforming to the ISO 4401-03-02-0-94
standard. The lever operated valve is also available in a
body ported version with 1/4" NPT port threads. The
solenoid and air operated valves are rated to a maximum
pressure of 315 bar while the lever operated valve is rated
to 400 bar. Maximum flow rates should not exceed 20
litres per minute.
Pressure Reducing Valves conforming to ISO 4401 are available in flange
or stackable mount configuration and compliment the directional valve
range. Maximum inlet pressure is 315 bar and five reduced pressure ranges
between 1 - 31.5 and 5 - 315 bar are available. Adjustment is by socket
head screw or hand knob.
Custom Solutions - While the standard range
of our air driven pumps covers a wide range of
applications we are always happy to look at
developing pumps for specific applications not
covered by standard products. In the past
specials have been produced for underground
mine operation, NACE approved units for sour
gas and pumps in stainless steel. If you should
have a special application then please contact
the technical staff at HEYPAC or your local
distributor who will be pleased to assist you.
Extended Suction Tube Kit including suction
strainer for use where basic pumps are being
installed in customer’s reservoir.
Noise Muffler Kit to reduce exhausting air noise
to a lower level than the standard exhaust silencer
fitted to every pump.
