GEKO-Pumpen
  • Offer Profile
  • We are a leading manufacturer of PTFE-lined chemical pumps according to DIN EN 22858 (Atex- and FDA-compliant) for the chemical and pharmaceutical industry.

    Our seal-less PTFE/PFA-lined chemical pump has been specially designed for pumping dangerous and chemically aggressive liquids. Because of using special materials the pumps are fit for FDA-applications. Absolute freedom from leakages and practically unrestricted corrosion resistance, even at temperatures of 170 °C are the outstanding advantages.
Product Portfolio
  • Pumps

  • Sustainable environmental protection!

    The GEKO-Pumpen GmbH contributes by development und manufacturing of their pumps for an active and sustainable environmental protection.

    To counter the increasing energy needs, our engineers have systematically improved the pumps to the required energy savings.

    With the following activities, the efficiency of the pumps was improved compared to convential lined pumps on the market:
    • Use of non-metallic isolation shells made of carbon fiber (without eddy-current losses).
    • Use of impellers with optimized shovels.
    • Use of otimized bearing materials.
      • Standardised Pumps

      • Centrifugal pump Type GEKONORM NM with magnetic drive

        The GEKONORM magnetic-pump is a PTFE/PFA-lined centrifugal pump according to DIN EN 22858 and has been specially designed for pumping dangerous and chemically aggressive liquids in an absolutely leak proof manner. Because of using special materials the pumps are fit for FDA-applications.

        Design:

        Without packing, single stage casing pump, in process design with magnetic drive. The closed impeller made of PTFE hast wo bearings. Slide bearings are made of silicium carbide. The thrust is absorbed by a thrust bearing. The defined side-stream guidance ensures that the medium circulates absolutely trouble-free.

        The power transmission is effected by permanent magnets. The pump is hermetically sealed and absolutely leak proof.
        • Operating temperature: up to 170° C (it depends on pump version)
        • Min. capacity: Q = 0,5 m3/h
        • Capacity: up to 200 m3/h (50 Hz)
        • Head: up to 90 m (50 Hz)
      • Peripheral pumps

      • Peripheral pumps Type GEKOBLOCK PM with magnetic drive

        The GEKOBLOCK-Peripheral pump with magnetic drive is seal-less side-channel pump. The pump is used whenever highly aggressive, toxic or dangerous fluids, without solids or crystalline particels need to be conveyed in an absolutely leak proof manner. The pumping fluid comes in tough only with PTFE, PFA, silicium carbide and ceramic.

        Design:

        The GEKOBLOCK magnetic pump is a single stage, PTFE close coupled, glandless leak proof pump. The PTFE impeller is horizontally adjustable on the ceramic shaft, which runs in silicium carbide bearings located at each shaft end.

        The power is transmitted via permanent magnets. The pump is hermetically sealed and absolutely leak proof.
        • Pump- sizes: 15-90, 25-100 und 25-140

        The pump size 25-140 is available in a bare-shaft and in a close coupled design. The sizes 15-90 und 25-100 are only available in close coupled design.
        • Operating temperature: T max. = 150° C
        • Min. capacity: Q =0,05 m3/h
        • Capacity: up to 10 m3/h (50 Hz)
        • Head: up to 90 m (50 Hz)
      • Close coupled pumps

      • Close coupled pumps Type GEKOBLOCK BM with magnetic drive

        In case of the modular concept, both pumps with a bear-shaft and ones with a block-type design can be used, and they are moreover interchangeable.

        Additionally we have the possibility to deliver pumps which are equivalent to the old QVF-pumps.
      • QVF-Pumps

      • We are able to deliver identical pumps for the former QVF-pump series (respectively SIHI isolined series).

        Additionally we have the possibility to deliver pumps which are equivalent to the old QVF-pumps.
