Product Description
RX Series Drainage Pumps
The RX Series Drainage Pumps provide reliable submersible pumping for clear water without abrasive particles. Pedrollo designed the range for domestic and civil drainage applications, including sump emptying, basement drainage and emergency floodwater removal across India.
Moreover, complete motor cooling supports dependable operation, while a double shaft-sealing arrangement helps protect the motor from the pumped liquid.
Stainless-Steel RX Drainage Pump Design
Pedrollo manufactures the primary pump components from stainless steel. Therefore, the pumps combine corrosion resistance, manageable weight and dependable operation in compatible clear-water applications.
The compact submersible construction allows the pump to operate directly inside a sump, tank or flooded area. Consequently, users do not require a separate suction pipe or priming system.

Together, these features support both permanent drainage installations and temporary emergency pumping.
RX Series Drainage Pump Performance
The complete range delivers flow rates up to approximately 320 litres per minute, equivalent to 19.2 m³/h. Selected models also develop discharge heads up to approximately 20.5 metres.
However, maximum flow and maximum head occur at different points on the hydraulic curve. Therefore, engineers should select the exact RX drainage pump according to the required duty point.
The published 50 Hz range includes motor outputs from approximately 0.25 to 1.1 kW.
Clear-Water and Small-Solids Handling
The Pedrollo RX pump can transfer clear water containing suspended solids up to approximately 10 mm.
Therefore, it can handle small particles commonly present in sumps, drainage water and compatible household wastewater.
However, the RX Series Drainage Pumps are not intended for sewage, sand, abrasive particles or long fibrous materials. For dirtier water containing larger solids, an RX-VORTEX or dedicated wastewater pump may provide a more suitable solution.
Stainless-Steel Construction
The outer sleeve, suction filter, diffuser, impeller, motor sleeve and motor cover use AISI 304 stainless steel.
In addition, Pedrollo manufactures the motor shaft from AISI 431 stainless steel. Consequently, the construction provides durability and corrosion resistance for compatible domestic and public drainage applications.
Double Shaft-Seal Protection
The RX Series Drainage Pumps use a double shaft-sealing system with an intermediate oil chamber.
RX 1–3 models combine a mechanical seal with an additional shaft seal. Meanwhile, RX 4–5 models use a double mechanical-seal arrangement.
Therefore, the sealing system provides an additional protective barrier between the hydraulic section and electric motor.
Motor and Electrical Options
The RX range uses two-pole motors designed for continuous-duty operation.
Single-phase RXm models include integrated thermal protection and a float switch. Three-phase RX models are also available for installations with a suitable control panel.
Moreover, RX-GM configurations use a compact magnetic float switch. Consequently, they can suit narrow sumps where a conventional swinging float has limited operating space.
RX Drainage Pump Operating Limits
Published range-wide limits include:
- Maximum flow: Up to 320 l/min
- Maximum head: Up to 20.5 metres
- Maximum solids size: 10 mm
- Maximum continuous liquid temperature: 50°C
- Intermittent liquid temperature: Up to 90°C for three minutes
- Maximum immersion depth: 10 metres
- Protection rating: IP68
- Motor insulation: Class F
- Continuous-duty rating: S1
However, installers should confirm model-specific cable length and operating requirements for deeper installations.
Low-Level Drainage Capability
RX 1, RX 2 and RX 3 models can drain water down to approximately 14 mm above floor level.
Larger RX 4 and RX 5 models leave a slightly higher residual level. Consequently, smaller models may suit basements, garages and utility areas where low final drainage levels are important.
However, the actual remaining water level also depends on the installation and float-switch arrangement.
RX Series Drainage Pump Applications in India
The RX Series Drainage Pumps may support applications across India such as:
- Basement flood removal
- Garage drainage
- Utility-area flooding
- Clear-water sump emptying
- Rainwater drainage
- Compatible household wastewater
- Washing-machine discharge
- Dishwasher wastewater
- Collection-tank emptying
- Public-building drainage
- Emergency water removal
- Automatic drainage systems
Nevertheless, appliance wastewater must remain within the pump’s temperature and solids-handling limits.
Installation Considerations
The RX pump can operate as a portable unit or in a permanent sump installation.
Installers should use correctly sized discharge piping and keep the pump stable on a clean base. In addition, the float switch needs sufficient space to move freely.
Moreover, users should avoid prolonged dry running and keep sand, wipes and long fibres out of the sump.
Selecting the Correct RX Drainage Pump
Correct selection depends on:
- Required flow
- Total dynamic head
- Sump dimensions
- Desired residual water level
- Electrical supply
- Liquid temperature
- Maximum particle size
- Installation depth
- Float-switch arrangement
- Portable or permanent installation
Therefore, engineers should select the RX Series Drainage Pumps from model-specific hydraulic data.
