The RL series progressing cavity pump belongs to Nova Rotors’ R series Wobble pumps from Italy. Let’s find out the special features of the progressing cavity pump line through the content below!
RL Wobble Pumps series of progressing cavity pumps
RL Series Wobble pumps are the ideal solution for those seeking a highly compact and versatile product. They can be used in a variety of industrial applications.
They are particularly easy and economical to maintain, due to the very small number of component parts. They can be used in a variety of industrial applications due to their ability to pump products which are viscous, which have solids in the fluid or which are mildly abrasive.They are also suitable for use within the food industry, as there are no dead zones within the pump.
Even at high rpm, they pump without pulsating and there is virtually no centrifugal effect.
The RL series range of pumps all have solidly constructed housings in cast iron and stainless steel (AISI Type 304 and AISI Type 316), manufactured using lost wax casting technology.
Threaded GAS BSP connections are available as standard, but we can also supply DIN 11851 type adaptors upon request.
Types of RL progressing cavity pumps
In the RL series, helical progressing cavity pumps are divided into 3 specific types as follows:
The RL Series
The RL Series: a highly compact product due to its integrated construction between pump and electric motor. It uses the patented Diamond Series joint, which guarantees exceptionally high reliability. The lantern between the pump housing and the drive has been removed to offer the benefit of a product which is compact and easy to maintain.
The RJL Series
The RJL Series: this is based on the same technology as the RL Series. However, in contrast, it uses support bearings with free bare shaft. The RJL series can be connected via the flexible coupling and is the ideal solution to supply as a bare shaft pump. The bearings ensure maximum reliability in all operating conditions.
The RFL Series
The RFL Series: this is based on the same technology as the RL Series. However, in contrast, it uses support bearings with a plug-in shaft at the inlet. The RFL Series can be directly connected to the drive via a flange. The ideal solution to supply as a bare shaft pump, while still maintaining a compact size and easy installation. The bearings ensure maximum reliability in all operating conditions.
