tapflo.comDuring each cycle the air pressure on the back of the discharging diaphragm is equal to the head pressure on the liquid side. Tapflo diaphragm pumps can therefore be operated against a closed discharge valve with no adverse effect to the life of the diaphragms. Suction One diaphragm creates a suction action when being pulled back from the ...

Double Diaphragm Pumps Concept and Theory
wwwd.graco.comDouble Diaphragm Pump Double Diaphragm Pumps use compressed air as the power source. They are frequently used for fluid transfer, low pressure spray, and other lower pressure applications requiring less than 120 psi (.85 MPa, 8.5 bar).

T8 - Air Pumping Ltd, diaphragm pump distributor
www.wilden-pumps.co.ukThe Wilden diaphragm pump is an air-operated, positive displacement, self-priming pump. These drawings show the flow pattern through the pump upon its initial stroke. It is assumed the pump has no fluid in it prior to its initial stroke. FIGURE 1 The air valve directs pres-surized air to the back side of diaphragm A.

sites.ntc.doe.govControl valves operated by an instrument signal are symbolized in the same manner as those shown previously, except the output of the controlling instrument goes to the valve actuator. Figure 4 shows a level instrument (designated "LC") that controls the level in the tank by positioning an air-operated diaphragm control valve.
Pressure Relief and Regulating Valves
www.sunhydraulics.compumps, or open center directional valves and fixed displacement pumps where fast response, low leakage and dirt tolerance are re-quired for shock pressure relief, consider direct acting valves. With equal or unequal displacement actuators consider: 1) Pilot operated valves for accurate pressure regulation 2) Direct acting valves for fast
BASIC HYDRAULIC SYSTEMS AND COMPONENTS
www.idc-online.comPumps powered by muscle are called hand pumps. They are used in emergencies as backups for power pumps and for ground checks of the hydraulic system. The double-action hand pump produces fluid flow with every stroke and is the only type used on Army aircraft. Handle to the Right. The double-action hand pump, shown in Figure 1-4, consists of a ...
Problem Solving - Centrifugal Pumps
www.stuartjohnsonco.comCentrifugal pumps are capable of evacuating (pumping) a modest amount of air from the suction side of the pump to the discharge side of the pump. Filling the inlet system with fluid or at least filling the pump (wetted pumping elements) will make a …
