6、 Double acting reciprocating pump

The piston moves to the right, sucking liquid in the lower left and draining liquid in the upper right. The piston moves to the left, draws liquid from the lower right, and draws liquid from the upper left. The piston reciprocates once, with two suction and discharge cycles, resulting in a more uniform flow rate.

7、 Pneumatic diaphragm pump

In order to prevent direct contact between the active column and the corrosive liquid, the cylinder chamber and the liquid material are separated by a diaphragm, which is essentially the principle of reciprocating pumps.

Performance characteristics:

Pneumatic diaphragm pump is a new type of conveying machinery and currently the most innovative type of pump in China. Using compressed air as the power source, for various corrosive liquids. Pneumatic diaphragm pumps are made of four materials: engineering plastic, aluminum alloy, cast iron, and stainless steel. Pneumatic diaphragm pumps use nitrile rubber, chloroprene rubber, fluororubber, polytetrafluoroethylene, and polytetrafluoroethylene according to different liquid media. To meet the needs of different users. Placed in various special occasions for pumping media that conventional pumps cannot pump, satisfactory results have been achieved.

(1) The pump will not overheat: compressed air is used as the power source, and during exhaust, it is a process of expansion and heat absorption. The temperature of the pneumatic pump decreases during operation, and no harmful gases are discharged.

(2) No electric sparks generated: Pneumatic diaphragm pumps do not use electricity as power and are grounded to prevent static sparks

(3) It can be achieved through liquid containing particles: because it works in a volumetric manner and the inlet is a ball valve, it is not easily blocked.

(4) Extremely low shear force on materials: how to suck in and how to spit out during operation, so minimal agitation on materials, suitable for conveying unstable substances

(5) The flow rate can be adjusted by installing a throttle valve at the material outlet.

(6) It has the function of self-priming.

(7) It can run empty without any danger.

(8) Can work underwater.

(9) The fluids that can be transported are extremely diverse, ranging from low viscosity to high viscosity, and from corrosive to viscous.

(10) There is no complex control system, no cables, fuses, etc.

(11) Small in size, lightweight, and easy to move.

(12) No lubrication is required, so maintenance is simple and there will be no pollution to the working environment due to dripping.

(13) The pump can always maintain high efficiency and will not decrease due to wear and tear.

(14) 100% energy utilization, when the outlet is closed, the pump automatically stops, causing equipment movement, wear, overload, and heating

(15) Without a dynamic seal, maintenance is easy and leakage is avoided. There are no dead spots during work.
