Thermoplastic centrifugal pumps with mechanical seal
Compact series KR sealPro up to 50 m3/h
This series is close-coupled. The pump is mounted directly to the motor flange by means of a plastic bracket. This compact execution is perfectly suited as stationary pump or for use in machines.
Compact series KR Chemical standard up to 500 m3/h
This series is close-coupled, but the bracket is made of metal for maximum stability. This compact execution, thanks to a reduced number of wear parts compared with conventional long-coupled pumps, requires less maintenance and related expenses. It is optional available in a vertical execution Model KrV.
Long coupled series TK Chemical standard up to 500 m3/h
This configuration consists of a bare shaft pump, fully assembled with a standard motor and flexible coupling on a normalized glass fiber-reinforced polyester base plate according DIN 24.259. Thanks to the design according to the “back pull out” system, the total mechanical part of the pump can be removed without disassembling the piping or motor. Therefore it is easy to open the pump for cleaning, inspection or maintenance. The alignment is not disturbed and no unnecessary work or costs is created.
all parts that come in contact with the liquid are machined from solid blocks of plastic. Thanks to a special production method and the lack of welds, there is no risk for chemical cracking, a major advantage compared to injection molded pumps. PP is the standard material and covers a wide range of duties. For highly abrasive liquids (high percentage of solids), on request impellers or housing parts of rCh- 1000/hMPE (high Modulus Polyethylene) can be supplied. For extremely corrosive mixtures at higher temperatures even a fully PTFE pump is possible. although the pump shaft is not in direct contact with the liquid, it is protected by a replaceable plastic shaft sleeve. The gaskets are standard made of EPDM but may be ordered in Viton or Viton/ PTFE-covered.
