CZPT Info for Air pushed liquid pumps
CZPT air pushed liquid pumps are ratio devices that use reduced force compressed
air driving a more substantial diameter piston (area x force) which is linearly related to a smaller
hydraulic piston/plunger. Making use of this ratio principal, a increased hydraulic strain can be created.
CZPT Pump model figures mirror the pumps nominal strain ratio, even though the technological data
indicates exact ratios. The outlet stall pressure is easy to set by modifying the air generate pressure
by means of a easy air pressure regulator.
By multiplying the pressure ratio by the accessible store
air pressure, the nominal liquid pressure can be calculated.
Exmple ( Pump Design: AH40 liquid pump)
Air generate piston area ( 160mm Ø)
CZPT plunger area ( 25 mm Ø)
Genuine ratio = forty:1
1. AIR Generate Area
The air travel section is made up of a gentle weight piston comprehensive 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 finish).
Under the control of pilot pins (poppet valve) activated at each end of the stroke
2. CZPT Part (Wetted End)
The hydraulic area of an air driven liquid pump consists of four principal parts, the hydraulic physique,
the piston/plunger, the check valves and the major high strain seal. The hydraulic
piston/plunger is directly joined to the air piston and it is housed within the hydraulic entire body and
its movement up and down generates the liquid circulation 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 greatest making it possible for fluid into the hydraulic human body and on the compression stroke the
inlet examine valve closes and the discharge check valve opens forcing the pumped fluid into the
method. The main high force seal is situated within the hydraulic human body and the piston/plunger seals
against this throughout operation. There are different resources and styles of higher force seals
relying on the fluid being pumped and the highest pressures of the pump, nonetheless the
CZPT seals are suitable for the two h2o and hydraulic fluid use.
CZPT air driven liquid pumps are self-priming, Nevertheless, higher ratio pumps are more difficult to
Prime and may require bleeding. In standard, it is not suggested to use an air- line lubricator.
CZPT air pushed liquid pumps cycle automatically as the outlet pressure increases the
resistance also boosts and the cycle price decreases until the pump stops routinely
when the output pressure forces are equivalent. This is referred to as the stall situation.
The pump will restart with a slight drop in the outlet stress or an increase in the air travel
force. Pump overall performance can be impacted by a quantity of conditions, this kind of as freezing of the
exhaust muffler or pilot valves (which is brought on by humidity in air lines), inadequate inlet air-line
sizes and soiled filers. When working the pumps on a continuous basis, we advocate you use
a maximum cycle price of 50~60 cycles for each minute.
This will the two increase service intervals and assist in preventing ice forming
at the exhaust. An air source dryer will also support in reducing icing up.
To get best total performance, it is advised not to lessen the indicated port measurements
and consult We for flow situations not shown in charts.
