Diaphragm Type Metering Pumps

Listing ID #3910257

In order to avoid leakage at the packing or seal particularly when a liquid is dangerous, toxic, or noxious, diaphragm pumps are used for metering. Diaphragm pumps have a diaphragm through which repeated compression / decompression motion is transmitted. The liquid does not penetrate through the diaphragm, so the liquid inside the pump is sealed off from the outside. Such motion changes the volume of a chamber in the pump head so that liquid enters through an inlet check valve during decompression and exits through an outlet check valve during compression, in a manner similar to piston pumps. Diaphragm pumps can also be made which discharge at fairly high pressure. Diaphragm metering pumps are commonly hydraulically driven.

Peristaltic pumps use motor-driven rollers to roll along flexible tubing, compressing it to push forward a liquid inside. Although peristaltic pumps can be used to meter at lower pressures, The diaphragm material is usually Teflon. The system is safety guarded by a in built Relief Vacuum Combancity Valve on the hydraulic side. For very severe duty conditions or when handling slurry or hot liquids, double diaphragm and remote heads can be provided.

The Company also manufactures Plunger Type Metering Pump for non-hazardous liquids, steam jacketed plunger type metering pump for molten liquid, remote head type metering pump for hot liquids. The Range includes high precision positive displacement pump conforming to API 675. Typical application for our pumps are useful for accurate dosing and mixing of acids, alcoholics, slurries, viscous liquids etc. They are used in Chemicals Plant, Fertilizer Plant, Water Treatment Plant, Soap Plant, Paper Industries, Pharmaceuticals Industries, Thermal Power Projects, and Plastic Industries.

Our range covers everything from the single pump to a completed automated Metering dosing system and comprises of plunger and diaphragm pump with metering range from various capacity and pressure from two to fifteen thousand LPH. pump can be offered in Simplex, Duplex, Triplex, and Multiple Heads, handling for different chemicals with a common Motor. Each head would have independent connection and capacity of each head can be also independently adjustable.
