Product Usage Instructions

Product Performance Range and Application Limits
The submersible pumps are suitable for short bursts of up to 3 minutes max for intermittent service, with a maximum application limit of 10 meters when using an appropriately sized power cable.

Product Installation
Follow the provided installation dimensions and weight specifications for proper setup. Ensure the pump is submerged correctly in the water source.

Product Maintenance
Regularly check and clean the suction filter, diffuser, and impeller to maintain optimal performance. Inspect the motor sleeve,shaft seal, and motor components for any signs of wear or damage.

Product Safety Precautions
Always disconnect the power supply before performing any maintenance tasks. Do not operate the pump continuously beyond its recommended limits to prevent overheating.

FAQ

• Can the pump be used for continuous operation?
  The pump is designed for intermittent service with short bursts of up to 3 minutes max. Continuous operation may lead to overheating and damage.

• What is the voltage requirement for the pump?
  The pump is available in single-phase (230 V) and three-phase (400 V) versions to suit different voltage requirements.

• Is the float switch included with all versions of the pump?
  The float switch is included for single-phase versions and can be requested for other versions if needed.

PERFORMANCE RANGE

• Flow rate up to 320 l/min (19.2 m3/h)
• Head up to 20.5 m

INSTALLATION AND USE

RX pumps are designed for efficiently draining clear wa-ter without abrasive particles. Their design ensures us-er-friendly operation and safe performance, thanks to complete motor cooling and a double shaft seal. Ideal for home and public applications, these pumps are perfect for permanent setups, quickly handling emergency situations like small floods in rooms, basements, and garages. They’re also great for managing household wastewater from dish- washers and washing machines, as well as for sump emp-tying.

APPLICATION LIMITS

• Maximum operating depth below water level up to 10 m (with an appropriately sized power cable)
• Liquid temperature up to +50 °C and up to +90 °C for short bursts (up to 3 minutes max) for intermittent ser-vice
• Capable of processing suspended solids up to Ø 10 mm
• Draining capability:
  • up to 14 mm from the bottom for RX 1-2-3
  • up to 25 mm from the bottom for RX 4-5
