Why choose a 3-screw pump?

SEIM 3-screw pumps are self-priming volumetric pumps suitable for transferring oils and liquids with a minimum lubricating action. The simplicity of the design makes them intrinsically reliable and efficient; the main characteristics that distinguish the product are:
  • extremely quiet operation
  • broad range of compatible viscosity
  • high operating speed = reduced pump size and costs
  • no pulsation
  • minimum sensitivity to particle pollution = maximum pump service life
  • high self-priming capacity
  • special functions for fluids containing emulsified air in the lubricating fluid
  • What are the standard delivery times?

    Various commodity categories are managed through our warehouse, exploiting our historical numbers and sales budget, generally guaranteeing immediate delivery of the goods; otherwise the average delivery time for these products is 4-5 weeks from the order date. Certain products, on the other hand, are basically managed by job order; in this case delivery dates range between a minimum of 6 to a maximum of 16 weeks for extremely "customised" products.

    What certificates can we produce?

    100% of SEIM products are inspected individually, monitoring and recording all main operating data.
    The production batch management system guarantees, following delivery of the goods, traceability of all production phases required to obtain the finished product.
    The following certificates are available:
  • Certificate of conformity
  • Declaration of Incorporation pursuant to Machinery Directive
  • Hydraulic testing certificate
  • Static testing certificate
  • Chemical analysis and composition of the main materials in accordance with standards EN10204
  • ATEX certificate of conformity
  • It is possible to request other certificates based on the various product types (ax. NDE welding analysis, testing based on customer specification, etc.)

    What warranties apply to SEIM products?

    The standard warranty for all SEIM products is 12 months of use (excluding parts subject to wear) or 18 months from the delivery date; different warranty terms must be agreed at the time of placing the order.
