Robot (DNP22-10BH) Submersible Pump

RD2110BH

The Robot RD range of Slurry submersible pumps are designed for pumping slurries and the transport of highly abrasive liquids.

Pumps are fitted with Vortex Impellers.

The Vortex impeller leaves a wide passage in the volute casing in which a strong vortex is created, this allows the entry of abrasive materials and reduces the chances of a blockage when fibrous materials are present, as they are thrown away from the edges of the impeller.

All the hydraulic components are manufactured from Ni Hard 4 which is harder than silica and quartz sand, and can therefore withstand impacts by rocks.

Some models can be fitted with agitators on the suction to enable the pumping of high density material.

Design Features

Motor class F (155°F/311°F).

Bearings - heavy duty, greased for life.

Shaft - stainless steel.

Shaft sealing - the seal area is protected from the pump by a special cover plate. Two independent mechanical seals, run in oil. At the pump side silicon carbide runs on ceramic, at the motor side carbon on ceramic.

Oil housing - with flexible rubber bellows.

Back vanes - prevent solids entering the seal area and reduce the pressure on the seals for longer seal life.

Impeller - virtually clog-free vortex type with wide un-obstructed passage in front.

No adjustments required - no jamming, constant high performance over a long period, with minimum maintenance.

Options include

Flame Proof motors - certified to European standards EN 50014/18/19 (BS 5501), class EEX de IIB T3 or T4, and to American FMRC standard, class 1, division 1, groups C&DT4.

Cooling jacket - for continuous dry running at full load, for external water supply only. Available for larger pumps. Seal flushing is optional.

Seal leak monitor - detects water ingress in both motor- and oil housing.

Thermostats - standard for all flameproof pumps, pumps with cooling jacket and the dredge versions, optional for all other pumps.

Dredge version - with agitator and hermetically sealed motor with terminal box, to allow cable replacement without opening the motor. Replacement of the mechanical shaft seals without opening the motor is possible.
