Drum pump – Lyes

for low viscosity chemicals

SKU: Drum pump - Lyes Categories: , ,


Product information “Drum pump – Lyes”

Motor: MI 4 – 500W, 230V (for a higher flow rate and head)
Immersion depth: 1000 mm (sealless)


The Drum pump is suitable for corrosive, aqueous to slightly viscous media. Perfect for siphoning or transferring caustic solutions.

  • Media examples: Sodium hydroxide, potassium hydroxide, ammonia water, formic acid and acetic acid etc.
  • Pump tube equipped with Lutz original hand wheel
  • Suitable for filling or transferring oils such as rapeseed oil and vegetable oil

Features & advantages

  • Optionally with electric or compressed air drive
  • No lubricants and therefore no contamination of the pumped medium by lubricants
  • Optimized Drum emptying
  • Universally resistant PTFE shaft bearings
  • Maintenance without special tools
  • Seal modules of the seal-less (SL) pump can be replaced

* The maximum flow rate is a value determined by means of a test bench and measured with water at a medium temperature of approx. 20 °C. The measurement is carried out at the pressure joint of the pump, without hose, nozzle or flow meter. The achievable flow rate in use is lower and depends on the individual application, the liquid properties and the configuration of the pump. The max. delivery head also depends on the pump design, motor and fluid. The viscosity values are determined with oil.

** Test assembly: Medium water / diesel, flow in preferred direction, settling section 0.2 m upstream and downstream of flow meter
