Heavy-duty peristaltic pumps - ideal for water and wastewater treatment

Granzow's pumps are equipped to serve a wide range of applications for water and wastewater treatment. Sludges, slurries, products with high solids media, and abrasives commonly found in municipal and industrial water treatment plants are easily transferred and metered. Our pumps are constructed using the newest peristaltic hose technology and premium materials to prevent leaks and minimize downtime.

Perfect for dosing highly corrosive products or transferring viscous sludges, slurries and high-solids media.

Key Benefits

  • Easy to assemble, operate and maintain
  • Highly resistant to abrasion when transferring sludges and slurries or harsh products such as lime milk and activated carbon
  • Simple, "straight-through" design, with no valves, vanes or impellers better handles viscous sludge with high-solid content
  • Gentle pumping for dosing polymers and flocculants
  • Precision dosing of abrasive slurries, flocculants or off-gassing liquids
  • Constructed with materials that are resistant to highly concentrated acids
  • Heavy-duty design allows 24/7 continuous use
  • Ability to pump gaseous products indefinitely
  • Operates without damage if supply lines run dry
  • Requires significantly less lubricant compared to shoe pumps
  • Low ownership costs due to the pump's long life and easily changeable wear resistant hoses

Common Applications

  • Dosing activated carbon and lime milk
  • Dosing and metering treatment chemicals such as sodium hypochlorite and ferric chloride
  • Dosing polymers and flocculants
  • Transferring ferric sludge from bottom of settling tanks to filter presses
  • Transferring rinse water that contains solids content
  • Removal of wastewater from overflow spillage ponds to main ponds for treatment
  • Sampling
Chemical peristaltic pump features
Chemical peristaltic pump features 1

Tefzel® (ETFE) coated front cover and housing

2

State-of-the-art hose available in EPDM or Hypalon®

Created with a unique manufacturing process that ensures perfect compression and quick installation. Precise performance even in extreme temperatures or abrasive/ corrosive conditions. Provides a longer hose life with fast, easy replacement.

3

Polypropylene or PVDF connections

4

Extremely heavy-duty design

Integrated oversized bearings to withstand axial loads paired with large metal rollers (also with oversized bearings) create the ideal pump for continuous working conditions. Offers unrivaled pump life and superior performance.

5

Hose-leakage sensor and drainage system

6

XXL roller technology

Excellent hose compression with no friction results in unmatched efficiency. Large rollers create a longer hose life, low energy consumption, minimal starting torque and a very wide frequency range. Generates major energy savings and a higher number of hose working hours.

7

Corrosion-resistant rollers and pump roller lip seals in EPDM

8

Easy to assemble, operate and maintain

Fast and simple assembly, commissioning and maintenance are possible thanks to an innovative design that allows for easy roller disassembly and quick hose replacement, resulting in less downtime. Only a small amount of lubricant is required producing minimal waste. Decreases cost and downtime.

Features may be configured to customer's unique application needs.
