Horizontal Internal Bearing

Internal Bearing RI series

Capacities upto 500 m3/hr
Pressures upto 40 bar

These pumps are designed for clean and lubricating media. The pumps are fitted with the bearings inside and the bearings are lubricated with the pumping media itself. Available in standard foot mounted configuration with sump heating arrangement as an option. Built in safety relief valve designed for 100% bypass.

Roto’s horizontal internal bearing Twin Screw pumps are available in standard foot mounted configuration with sump heating arrangement as an option.

These pumps are selected where the fluids are clean and have lubricating properties.

Mechanical seals are standard. Option for gland packing is also available. Pumps are fitted with relief valves suitable for 100% bypass. The suction and discharge ports are in-line.

CASING:
• Cast Iron, • Cast Steel, • Fabricated  Steel • Fabricated Stainless Steel.
LINER:
• Case Steel, • Stainless Steel.
SCREWS:
• Alloy Steel • Stainless Steel, • Hardened Steel.
TIMING GEARS:
• Hardened Steel.
OTHER EXOTIC MATERIALS:
• Duplex • Super Duplex .
SCREW SURFACE COATING:
• Hard Chrome Plating.

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.
