Roto Xtra Value Progressive Cavity Pumps are designed to pump ‘tough – to – handle’ fluids with ease in varied industries. The construction of these pumps is based on the modular concept and comprises of next generation pumping elements i.e. Rotor, Stator, Solid Shaft and Double Sealed Cardan Universal Joints for improved performance and longer service life.

These pumps are available in bare shaft and close coupled configuration. Selected pump sizes are available with 6 stages and 8 stages.. Options also available with different material grades and shaft sealing.

Single Stage Pump

Capacity: up to 500 m3/hr

Pressure: up to 6 bar

These Heavy Duty cost effective pumps use the extended Rotor, Stator Geometry and results in lower rubbing velocities which are ideal for various applications.

Multi Stage Pump

Capacity: up to 250 m3/hr

Pressure: up to 48 bar

These heavy duty pumps are designed for continuous or intermittent duty and are suitable to perform efficiently even for the most difficult fluid handling applications in various industries.

Dry Running Protection Device:

To prevent the stator damage due to dry running, specially developed temperature sensor is screwed into the stator wall to monitor the operating temperature. If by any chance the pump runs dry, the stator temperature would increase. Roto DRP would switch off the pump at pre set temperature.

Pressure Switch:

To prevent the pump from damage due to over pressurization in the discharge as well as low pressures beyond the capability of the pump. This system trips the pump and protects the pump as well as the system.

Gauges (Pressure, Vacuum, and Differential):

These devices are especially important for the system with dynamic working characteristics, that require constant monitoring. The selection of gauge requires consideration of process, environment, accuracy, dial size, connection & mounting. It is advised to limit the normal working pressure to 25-75% of the scale of the gauge.

 

Relief Valves:

In addition to relieving excess pressure from closed-top vessels or piping systems, these normally closed valves provide system control benefits. It is versatile and widely utilized valve. Its compact size, ease of setting, readjustment and repeatability, all contribute to its popularity. The pressure setting is done manually.

 

Strainers:

A Strainer is an inexpensive “insurance” for protecting pumps. There is often unwanted matter present which can cause serious problems. Dust, foreign matter or even clumps of product itself, can clog or damage critical & expensive equipment. Another factor to consider is the cost of downtime.
