F 716 Submersible Centrifugal Pump

Stationary circulation and filter pump with impeller for flow rates up to 750 l/min in a compact design.

The F 716 submersible centrifugal pump conveys and circulates both neutral and chemically aggressive liquids. It is suitable for stationary applications in the chemical industry, process engineering, electroplating, water treatment, and wastewater post-treatment.

The pump operates seal-free within the fluid zone. The free-floating shaft requires no bearings or seals in contact with the fluid. This reduces wear points and supports reliable continuous operation.

Features

  • Stationary circulation and filter pump with impeller
  • Suitable for neutral and chemically aggressive liquids
  • Seal-less in the fluid zone
  • Free-floating shaft without bearings or seals in the fluid-contacting area
  • The motor shaft also serves as the pump shaft
  • Robust riser pipe firmly connected to the mounting flange
  • Low-vibration operation thanks to sturdy construction
  • Aerodynamically optimized impellers in various diameters
  • With mounting flange for stationary use
  • Available in four sizes: 115, 135, 185, and 230
  • Available as a standpipe or rod version
  • Outer tube made of polypropylene or polyvinylidene fluoride
