A mechanical seal is simply a method of containing fluid within a vessel (typically pumps, mixers, etc.) where a rotating shaft passes through a stationary housing or occasionally, where the housing rotates around the shaft.

The centrifugal pump is the most used pump type in the world. The principle is simple, well-described and thoroughly tested, and the pump is robust, effective and relatively inexpensive to produce. An increase in the fluid pressure from the pump inlet to its outlet is created when the pump is in operation. This pressure difference drives the fluid through the system or plant. The centrifugal pump creates an increase in pressure by transferring mechanical energy from the motor to the fluid through the rotating impeller. The fluid flows from the inlet to the impeller centre and out along its blades. The centrifugal force hereby increases the fluid velocity and consequently also the kinetic energy is transformed to pressure. Like most pumps, a centrifugal pump converts rotational energy, often from a motor, to energy in a moving fluid. A portion of the energy goes into kinetic energy of the fluid. Fluid enters axially through eye of the casing, is caught up in the impeller blades, and is whirled tangentially and radially outward until it leaves through all circumferential parts of the impeller into the diffuser part of the casing. The fluid gains both velocity and pressure while passing through the impeller. The doughnut-shaped diffuser, or scroll, section of the casing decelerates the flow and further increases the pressure. Key features OF CENTRIFUGAL PUMP The pumps are simple to clean and maintain. The pump casing being removable in a matter of seconds without the use of tools. Impeller, mechanical seal can be changed without difficulty & replacement parts are available ex-stocks. End connections can be flanged, SMS/DIN type fittings etc.

Gear pumps are a type of rotary positive displacement pump, meaning they pump a constant amount of fluid for each revolution. Gear pumps transfer fluid by gears coming in and out of mesh to create a non-pulsating pumping action. Gear pumps are able to pump at high pressures and excel at pumping high viscosity liquids efficiently. There are no valves in a gear pump to cause friction losses and also high impeller velocities, with resultant friction losses, are not required as in a centrifugal pump. Therefore a gear pump is well suited for handling viscous liquids such as fuel and lubricating oils. Gear pumps are not suited for pumping solids and abrasive liquids. As the gears rotate they separate on the intake side of the pump, creating a void and suction which is filled by fluid. The fluid is carried by the gears to the discharge side of the pump, where the meshing of the gears displaces the fluid. The mechanical clearances are small— in the order of 10 μm. The tight clearances, along with the speed of rotation, effectively prevent the fluid from leaking backwards.

  our range of highly-polished, stainless steel (304 or 316l) pumps have been specifically developed for applications that demand the highest standards of hygiene and contamination control in a clean and sterile environment centrifugal pumps apply centrifugal force to generate velocity, use rotating impellers to increase velocity, and push fluids through an outlet valve. Positive displacement pumps use rollers, gears, or impellers to move fluid into a fixed cavity so that when liquid exists, the vacuum that is created draws in more fluid. Jet pumps force fluid through a nozzle, converting the fluid’s energy into velocity energy. Airlift pumps mix air or gas with the liquid media so that the air-liquid mixture, with a lower specific weight than the liquid, rises in the pipe and is discharged above the level of the liquid. application of sanitary centrifugal pumps milk | butter milk | sugar syrup | softdrinks | pharma syrup | mineral water | fruit juice 

A metering pump moves a precise volume of liquid in a specified time period providing an accurate flow rate. Delivery of fluids in precise adjustable flow rates is sometimes called metering. The term "metering pump" is based on the application or use rather than the exact kind of pump used, although a couple types of pumps are far more suitable than most other types of pumps. Most metering pumps are oscillating displacement pumps. An exactly defined volume of liquid is drawn into the displacement body on the reciprocal stroke and forced into the metering line on the compression stroke. The pump settings can be changed to achieve consistently accurate metering.   APPLICATION OF METERING PUMPS Chemicals | Potable Water Treatment | Cooling Circuits | Waste Water Treatment | Paper Industry | Plastic Manufacturing etc..
