What is the OVELL pneumatic diaphragm pump used for?

　OVELL Pneumatic Diaphragm PumpIt is a new type of conveying machinery, usually powered by compressed air. It has powerful functions, combining many advantages of self-priming, submersible, mud, centrifugal, and plunger pumps. It can transport various corrosive liquids, large particle liquids, and high viscosity, volatile, flammable, and toxic liquids.

Since the birth of the OVELL Pneumatic Diaphragm Pump, it has gradually penetrated other markets and occupied a part of them. For example, it has already taken a major position in the paint and ceramics industry, and in other industries such as environmental protection, wastewater treatment, construction, sewage treatment, and fine chemicals, it is expanding its market share and has an irreplaceable position.

1. Features of the OVELL Pneumatic Diaphragm Pump

1. Compressed air is the power source.

2. It is a volumetric pump, and the volume changes due to the reciprocating deformation of the diaphragm. Its principle is similar to that of a plunger. Due to the characteristics of the principle, it has the following features:

(1) Will not overheat: powered by compressed air, the exhaust is an expansion heat-absorbing process. The temperature decreases, and no harmful gases are discharged.

(2) No electric sparks: no electricity, grounding prevents static sparks.

(3) Can pass liquids containing particles: because it is volumetric, the inlet is a ball valve, which is not easily blocked.

(4) Very low shear force on materials: it sucks in and spits out the same way, so the stirring of materials is minimal, suitable for transporting unstable substances.

(5) Flow rate is adjustable, and a throttle valve can be installed at the outlet to adjust the flow rate.

(6) Can run without load, posing no danger.

(7) Can operate submerged.

(8) Can transport various fluids, from low viscosity to high viscosity, from corrosive to viscous.

(9) Complex control system, no cables, fuses, etc.

(10) Small size, lightweight, easy to move.

(11) No lubrication required, simple maintenance, and will not pollute the environment due to leakage.

(12) Can always maintain high efficiency, not reduced by wear.

(13) 100% energy utilization rate. When the outlet is closed, it stops, and the equipment does not move, wear, overload, or generate heat.

(14) No dynamic seals, simple maintenance, avoiding leakage.

2. Advantages of the OVELL Pneumatic Diaphragm Pump:

1. Since it is powered by air, the flow rate can be adjusted with changes in back pressure (outlet resistance), suitable for medium to high viscosity fluids. However, centrifugal pumps are based on water. If used for fluids with slightly higher viscosity, a reducer or frequency converter is needed, which greatly increases costs.

2. In harsh construction sites, such as construction sites and industrial sites where wastewater is discharged, due to the many impurities and complex components in the wastewater, pipes are easily blocked, causing electric pumps to overload, and motors to heat up. It can automatically stop when the flow rate is adjustable until the pipe is blocked.
