CZPT Data for Air driven liquid pumps


CZPT air driven liquid  pumps are ratio products that use lower strain compressed


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


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


CZPT Pump design figures mirror the pumps nominal force ratio, while the technical data 


implies actual ratios.  The outlet stall force is easy to set by altering the air push force


by way of a simple air force regulator. 


By multiplying the strain ratio by the available shop


air pressure, the nominal liquid stress can be calculated.


Exmple ( Pump Product: AT644 liquid pump)


Air drive piston region ( 160mm Ø)


CZPT plunger location ( 20 mm Ø)


Genuine ratio = sixty four:1


1.  AIR Travel Section


The air drive section consists of a light excess weight piston full with seals running 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 stop).


 Under the control of pilot pins (poppet valve) brought on at every finish of the stroke


2. CZPT Area (Wetted End)


The hydraulic part of an air driven liquid pump is made up of 4 major parts, the hydraulic human body,


the piston/plunger, the verify valves and the principal large strain seal. The hydraulic


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


its motion up and down results in the liquid flow into and out of the pump via the check


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


 opens to the optimum enabling fluid into the hydraulic human body and on the compression stroke the


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


method. The major higher force seal is located inside of the hydraulic human body and the piston/plunger seals


against this for the duration of operation. There are distinct materials and types of large pressure seals


dependent on the fluid becoming pumped and the maximum pressures of the pump, nevertheless the


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


CZPT air pushed liquid pumps are self-priming, However, substantial ratio pumps are more tough to


Prime and may possibly demand bleeding. In basic, it is not advisable to use an air- line lubricator.


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


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


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


The pump will restart with a slight drop in the outlet force or an improve in the air drive


force. Pump performance can be impacted by a quantity of problems, these kinds of as freezing of the


exhaust muffler or pilot valves (which is caused by humidity in air lines), inadequate inlet air-line


measurements and dirty filers. When working the pumps on a constant foundation, we suggest you use


a highest cycle fee of 50~60 cycles for every minute.


This will each increase provider intervals and aid in stopping ice forming


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


To receive ideal overall functionality, it is advisable not to lessen the indicated port sizes


and consult We for stream circumstances not revealed in charts.
