F 640 PP Submersible Centrifugal Pump

Tank pump with conical rotor or impeller for flow rates up to 700 l/min.

The F 640 PP submersible centrifugal pump handles large volumes of highly flammable liquids from containers, tanks, and open basins. It is suitable for chemically aggressive media in the chemical industry, process engineering, surface engineering, and water and wastewater treatment.

The polypropylene outer casing enables use with acids, alkalis, and other aggressive fluids. Depending on the pumping application, the pump is available with an open cone rotor or a closed impeller.

Features

  • Available with an open cone rotor or a closed impeller
  • Two sizes with cone rotor: 15 and 30
  • Two sizes with impeller: 15Z and 30Z
  • Mounting flange with an outer diameter of 265 mm
  • Construction consisting of an inner tube, outer tube, and drive shaft
  • Drive shaft mounted in the inner tube
  • Outer tube made of polypropylene
  • Can be installed in a pressurized tank or gas scrubber
  • Mechanical seal made of oxide ceramic/SiC
  • O-rings made of FKM
  • Steel core in the inner tube reduces thermal expansion between the inner tube and the pump shaft

Advantages

  • Safely pumps chemically aggressive liquids from tanks and open basins
  • Suitable for tall tanks up to 4.1 m without a bottom opening
  • Also pumps fluids containing solids
  • Can be used both as a mobile and stationary unit
  • Motor can be replaced if necessary
  • Hermetically sealed design enhances process reliability
  • Variants with a conical rotor or impeller cover different performance ranges
  • The polypropylene version is suitable for many chemical applications
