Dosing / Metering Pump

These pumps are used for exact metering of fluid

  • MOC:Wetted parts - stainless steel 316, 304, 316l, 304l gland, Sealings - PTFE
  • Applications:Sugar,paper, fertilizer, power, food pharmaceuticals, oil & gas industries

Screw Series Pump

Screw series pump are progressive cavity type pump.

  • Application:liquid with heavy viscocity like molasses in sugar industries, maximum permissible solid content upto 50%
  • MOC :Housing - S.S., CI. hastalloy
  • Stator :Natural rubber, Neoprene, Nitrile, Viton
  • Rotor:Normally hardened & chrome plated, S.S.

Dosing System on Skid

A typical dosing system incorporates the following parts solution preparation tank single or compartmented dosing pumps single or multiple stirrer valves fitting interconnecting piping instruments like pressure gauges,level gauge control panel

Centrifugal Pumps

  • Type:Radialflow, Axialflow

Pumps are commonly rated by horsepower, flow rate, outlet pressure in metres (or feet) of head, inlet suction in suction feet (or metres) of head. The head can be simplified as the number of feet or metres the pump can raise or lower a column of water at atmospheric pressure.

From an initial design point of view, engineers often use a quantity termed the specific speed to identify the most suitable pump type for a particular combination of flow rate and head.

Pump Material

The pump material can be Stainless steel (SS 316 or SS 304), cast iron etc. It depends on the application of the pump. In the water industry and for pharma applications SS 316 is normally used, as stainless steel gives better results at high temperatures

Submerssible Pumps

The submersible pumps used in ESP installations are multistage centrifugal pumps operating in a vertical position.

The pump itself is a multi-stage unit with the number of stages being determined by the operating requirements. Each stage consists of a driven impeller and a diffuser which directs flow to the next stage of the pump. Pumps come in diameters from 90mm (3.5 inches) to 254mm (10 inches) and vary between 1 metre (3 ft) and 8.7 metres (29 ft) in length. The motor used to drive the pump is typically a three phase, squirrel cage induction motor, with a nameplate power rating in the range 7.5 kW to 560 kW (at 60 Hz).

Vacuum Pumps

Pumps can be broadly categorized according to three techniques:

  • Positive displacement pumps use a mechanism to repeatedly expand a cavity, allow gases to flow in from the chamber, seal off the cavity, and exhaust it to the atmosphere.
  • Momentum transfer pumps, also called molecular pumps, use high speed jets of dense fluid or high speed rotating blades to knock gas molecules out of the chamber.
  • Entrapment pumps capture gases in a solid or adsorbed state. This includes cryopumps, getters, and ion pumps.
