Wide Throat PC Pump

About Products

Wide Throat type inlet allows gravity flow of highly viscous (plastico – Viscous) material on to the augur-on-coupling rod which pushes the substance to the pumping element. Wide Throat Pumps with the twin paddle bridge breaker arrangement at the top are designed for handling extremely difficult media with very high solid content and non – flowing properties.

Available in close coupled and bare shaft configuration. Custom designed hopper is also available on requirement. A variety of construction materials and shaft sealing options are also available.

Standard Hopper & Oversized Hopper

Capacity: up to 200 m³/hr
Pressure: up to 36 bar

Accessories

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.
