Summary

Product Identification

• Product Line: RS Series
• Types:
  • RS D Series Residue Dewatering Pump
  • RS Series Multipurpose Submersible Pump
• Models: RSD-400, RS-50, RS-50A, RS-100, RS-100A, RS-150, RS-150A, RS-250, RS-250A, RS-400, RS-400A

Features

• Lightweight (e.g., RSD-400 dry weight only 9.5 Kgs), easy to carry, and high efficiency.
• Double frame casing with a circumferential flow system ensures superior cooling effect.
• Outer cover made of stainless steel.
• Best-performed silicon mechanical seal for excellent sealing.
• Long-lasting durability for continuous running.
• Epoch-making design of bottom strainer enables suction of residue water up to 2 mm in height from the ground.
• Equipped with a typical swing check valve and valve sheet at the suction side, preventing water from returning once sucked, even if the pump stops.
• Bottom plate includes cushion rubber to prevent damage to pit surfaces, even if made of fiberglass reinforced plastics.
• Rust-Proof and Acid-resistant, suitable for sea water, light chemical, and food industries.
• Motor with built-in Overload Protector.
• "A" models feature a latest designed electronic floatless level controller for automatic operation, suitable for permanent installation.
