number of products that were made by the company. Their
range of diesel engines, hydraulic and pneumatic
products was very large. I hope the few images that are

An Air-Operated Hydraulic Pressure Testing Pump
A compact small pump, designed
for use with high pressure hydraulic testing
equipment which is now being made by the Turner
Manufacturing Company, Limited, Villiers Street,
Wolverhampton, is illustrated in the accompanying
engraving. It is designed for coupling directly to
existing factory air lines, and serves as an
intensifier which uses the pressure of the air to
raise the oil or water in the hydraulic system to a
||The pump has two cylinders arranged vertically
in tandem, the pistons in each cylinder being
coupled together by a common connecting rod. The
piston in the lower cylinder is actuated by the
compressed air and it has a considerably larger
surface area than the upper piston.
Air is supplied to the double acting lower
cylinder through a ported rotary valve, which is to
be seen on the side of the upper cylinder in the
illustration. This valve is operated through a push
rod connected to the air piston and projecting
upwards through the cylinder cover. The air valve
spindle is balanced by a spring and is unaffected by
the air pressure. This arrangement avoids any
tendency it might have to stick when being swung
In order to save time when filling the hydraulic
system, the hydraulic inlet and outlet valves have
been designed to lift at relatively low pressures so
that liquid from the mains supply can flow straight
through the pump.
Once the pressure in the system equals that of
the mains supply, the pump begins forcing the
pressure up to the required figure. The pump
operates continuously until the maximum pressure is
reached when it stops automatically.
It holds the pressure
indefinitely without any loss, but if the hydraulic
pressure is lowered during the test the pump
restarts automatically. An air-reducing valve which
can be fitted to the unit permits an infinite
variation of air pressure up to the maximum of the
Pumps are made in two types,
each working with an air supply of 80 lb per square
inch. One pump delivers liquid at 750 lb per square
inch at a rate of 4.5 cubic inches per stroke, and
the other at 2,000 lb per square inch at 1.7 cubic
inches per stroke. Higher air pressures of up to 100
lb per square inch may be used to give
correspondingly increased hydraulic pressures.
