CZPT Info for Air driven liquid pumps


CZPT air driven liquid  pumps are ratio gadgets that employ lower pressure compressed


air driving a greater diameter piston (region x pressure) which is linearly connected to a smaller sized


hydraulic piston/plunger. Using this ratio principal, a increased hydraulic strain can be produced.


CZPT Pump product figures reflect the pumps nominal force ratio, while the technical data 


indicates exact ratios.  The outlet stall pressure is straightforward to set by changing the air travel pressure


through a straightforward air pressure regulator. 


By multiplying the force ratio by the obtainable store


air pressure, the nominal liquid force can be calculated.


Exmple ( Pump Design: AT644 liquid pump)


Air travel piston region ( 160mm Ø)


CZPT plunger region ( 20 mm Ø)


True ratio = sixty four:one


one.  AIR Drive Segment


The air generate part consists of a gentle bodyweight piston complete with seals managing within 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) activated at each finish of the stroke


two. CZPT Part (Wetted End)


The hydraulic section of an air pushed liquid pump is made up of 4 major parts, the hydraulic physique,


the piston/plunger, the examine valves and the primary high stress seal. The hydraulic


piston/plunger is  directly linked to the air piston and it is housed within the hydraulic physique and


its movement up and down produces the liquid movement into and out of the pump by means of the examine


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


 opens to the maximum enabling fluid into the hydraulic entire body and on the compression stroke the


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


procedure. The principal large force seal is located within the hydraulic body and the piston/plunger seals


against this for the duration of operation. There are various resources and designs of large force seals


dependent on the fluid currently being pumped and the optimum pressures of the pump, nonetheless the


CZPT seals are suitable for equally h2o and hydraulic fluid use.


CZPT air driven liquid pumps are self-priming, Nevertheless, high ratio pumps are a lot more hard to


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


CZPT  air driven liquid pumps cycle automatically  as the outlet strain will increase the


resistance  also increases and the cycle charge decreases until finally the pump stops immediately


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


The pump will restart with a slight drop in the outlet strain or an increase in the air drive


strain. Pump overall performance can be influenced by a amount of circumstances, this sort of as freezing of the


exhaust muffler or pilot valves (which is triggered by dampness in air traces), insufficient inlet air-line


dimensions and soiled filers. When operating the pumps on a constant foundation, we recommend you use


a greatest cycle price of 50~60 cycles per moment.


This will both enhance services intervals and assist in avoiding ice forming


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


To acquire best overall overall performance, it is advised not to reduce the indicated port sizes


and consult We for stream situations not proven in charts.
