E - SEMI-SUBMERSIBLE PUMPS

POISED TO DIVE

SEEPEX semi-submersible pumps empty barrels, pits, basins and containers – efficiently, thoroughly, and environmentally friendly. They can even withstand the demands of abrasive or corrosive media with low to high viscosity. This makes them a cost-effective alternative to conventional pump systems, particularly in applications with critical suction heads or limited installation space.

Features and Benefits

Different installation depths

Available in different designs for different immersion depths – all the way through to fully submersible pumps

Environmentally friendly

Suitable for installation in closed systems and compliant with environmental protection regulations thanks to its gas-tight domed lid

Gentle conveyance

Low-pulsation, constant flow rate for consistent product quality

Optimizing processes

It is possible to increase the NPSHa for liquids with low vapor pressure without cavitation - by installing the pump in a vessel

Versatile applications

Ideal for numerous applications in the chemical industry, but also for certain conveying processes in the food, pharmaceutical and cosmetics industries

Technologies, accessories and options

  • Options
null

  • Tie bolts/screw

    Corrosion proof, optional available in stainless steel design.

  • Rotor

    Wear resistant and corrosion-resistant materials. Optionally with hard surface treatment.

  • Conventional geometry

    With short pitches and a compact design, the conventional geometry produces high pressures.
    null

  • 6L geometry

    With a small rotor diameter and a long pitch, the 6L geometry attains lower surface velocities and extends the service life due to its large sealing line.
    null

  • Tricam geometry

    The rotor with Tricam geometry features a three-helix geometry. This enables it to achieve larger conveying capacities with the same overall length of the pump.
    null

  • Stator

    In food-grade materials according to FDA, and in compliance with EHEDG directives. Follows pharma regulations according to several USP classes.

    null

  • Equal Wall Stator

    The stator with uniform wall thickness is used in situations with very high pressures or temperatures.
    null

  • Universal joint sleeve with holding bands

    Protects the grease-filled joints from penetration of the liquid pumped, even in case of maximum vacuum or pressure loading. Streamlined design to reduce turbulence and NPSHr.

  • Coupling rod

    For power transmission. Improved design, optional special designs available.

  • Pressure casing

    With connections for pressure/vacuum gauge and mounting plate for fixing the pump. Flange connections in DIN or ANSI. Length according to customers specification.

  • Shaft sealing

    Single-acting mechanical seal, independent of direction of rotation, with quench and supply tank (78 cm / 3 to 4 l) to protect the sliding surface against dry running.

  • Drive

    Geared motors, variable speed drives or frequency controlled motors of all major manufacturers, directly flanged to the pump without additional couplings or guards. Covers made of stainless steel are available.

  • Overpressure Protection

    The pressure gauge switches off the pump as soon as a pre-set pressure is exceeded or not reached and protects the pump from increased wear and tear or piping damage.
    null

  • Cartridge mechanical seal

    Ready-to-install pre-assembled units with supply connections and attachment brackets for quick replacement.
    null

  • Single-acting mechanical seal

    Universal standard mechanical seal for dosing, food applications and semi-submersible pumps for sealing the plug-in shaft in the suction casing or the hopper.
