CZPT Details for  pneumatic driven hydraulic pump  


CZPT air pushed liquid  pumps are ratio gadgets that make use of low pressure compressed


air driving a bigger diameter piston (region x force) which is linearly related to a smaller sized


hydraulic piston/plunger. Utilizing this ratio principal, a higher hydraulic strain can be produced.


CZPT Pump design figures replicate the pumps nominal pressure ratio, while the technical data 


signifies exact ratios.  The outlet stall strain is simple to established by changing the air travel strain


via a basic air pressure regulator. 


By multiplying the stress ratio by the offered shop


air pressure, the nominal liquid stress can be calculated.

Air generate piston location ( 100mm Ø)


CZPT plunger spot ( 20 mm Ø)


Real ratio = 25:1


1.  AIR Generate Segment


The air travel area is made up of a light fat piston full with seals managing inside an


aluminum barrel. The diameter of the air piston is 80mm. When compressed air is supplied to


the pump the air pushes the air piston down on a compression stroke


( forces fluid out of the liquid conclude).


 Under the control of pilot pins (poppet valve) brought on at each end of the stroke


two. CZPT Section (Wetted End)


The hydraulic segment of an air pushed liquid pump is composed of 4 major items, the hydraulic body,


the piston/plunger, the check out valves and the principal substantial force seal. The hydraulic


piston/plunger is  directly linked to the air piston and it is housed inside of the hydraulic entire body and


its movement up and down creates the liquid flow into and out of the pump by way of the verify


valves. The examine valves are spring loaded and on the suction stroke the inlet check valve


 opens to the greatest permitting fluid into the hydraulic body and on the compression stroke the


inlet check out valve closes and the discharge check valve opens forcing the pumped fluid into the


method. The major higher force seal is situated in the hydraulic physique and the piston/plunger seals


against this during procedure. There are various components and designs of higher strain seals


depending on the fluid currently being pumped and the maximum pressures of the pump, however the


CZPT seals are suitable for equally water and hydraulic fluid use.


CZPT air pushed liquid pumps are self-priming, Nevertheless, large ratio pumps are much more challenging to


Prime and could call for bleeding. In basic, it is not advised to use an air- line lubricator.


CZPT  air pushed liquid pumps cycle automatically  as the outlet force boosts the


resistance  also will increase and the cycle charge decreases right up until the pump stops instantly


when the output  pressure forces are equivalent. This is referred to as the stall problem.


The pump will restart with a slight drop in the outlet strain or an boost in the air travel


stress. Pump efficiency can be afflicted by a variety of conditions, these kinds of as freezing of the


exhaust muffler or pilot valves (which is brought on by humidity in air strains), insufficient inlet air-line


measurements and filthy filers. When running the pumps on a continuous basis, we recommend you use


a maximum cycle rate of 50~60 cycles per moment.


This will the two boost provider intervals and support in protecting against ice forming


at the exhaust. An air offer dryer will also aid in lowering icing up.


To obtain very best all round efficiency, it is suggested not to lessen the indicated port dimensions


and consult We for movement situations not demonstrated in charts.
