V MODULAR Sealless Magnetic Drive Pump for Chemical Processing ApplicationsV MODULAR

Pump construction

Close-coupled configuration allows conventional drivers to be mounted directly to pump frame. No base, coupling or guards are required for this mounting.

Sealless sliding vane multistage modular pump with permanent magnet drive system, no mechanical seal.

A modular range of pumps covers various performances — ideal for sampling and low-viscosity liquids.

The isolation shell separates the liquid chamber from the atmosphere — perfect for aggressive, explosive, and toxic liquids, hydrocarbons, and heat transfer fluids. Ideal for chemical, petrochemical, and refinery industries.

Epoxy primer and polyacrylic enamel (water-based) for high-quality corrosion resistance and environmental compliance.

Available connections: Threaded BSP (GAS), NPT, DIN Flanges PN25/PN40, ANSI Class 150/300/600. Mounting feet support B3B5 or B5 motor versions.

An elastic coupling between stages absorbs shocks and increases cartridge life. CNC-machined stainless steel components ensure precision, while elastomers are application-specific.

Pump casing and cover: Stainless Steel 316 solid bar, precision-machined for tight tolerances.

HP Lip Seal: Contains pressure between stages.

Sealing system: Flat gaskets in various materials:

  • Asbestos-free
  • PTFE (standard)
  • Graphoil
  • GYLON®

Rear shell: One-piece, ellipsoidal profile — stronger than traditional shells. Options: AISI 316 (standard), Hastelloy® C276 (high pressure), or Titanium alloy (for higher pressure/efficiency).

Magnetic coupling: High-power synchronous design using rare earth magnets, locked mechanically. Handles liquids up to 392 °F (200 °C).

Quick Change Cartridge Kit

Designed for fast, easy maintenance.

Standard version “1 SiC” (for low viscosity): Cartridge with metallized carbon, rotor Duplex 22% Chrome, and SiC bearings.
