A Verderflex peristaltic dosing pump is a positive-displacement pump that uses a flexible tube or hose through which fluid flows. Inside the pump, a rotor (with rollers or shoes) compresses the tube in a cyclic motion — as the part of the tube is squeezed, liquid is expelled, and as the tube recovers, it draws in more fluid.

Key features include:

• Seal-less design: The fluid only contacts the inner surface of the tube or hose, not any mechanical parts or seals. 

• Low maintenance: The only wear part is the hose or tube, which is relatively inexpensive to replace.

• Self-priming & dry-running: It can draw liquid in from suction (self-priming) and can run without fluid present without damage.

• Gentle pumping action: Because the pumping action is gentle (low shear), it’s suitable for shear-sensitive or delicate fluids (e.g., polymers, biological fluids).High suction lift: It can generate a strong suction, allowing it to lift fluid from a low source. 

• Abrasion resistance: The Verderflex hose is designed to handle abrasive or corrosive media; its fatigue resistance is optimized to give long hose life.Solids handling: Certain Verderflex hose pumps can handle slurries or fluids with suspended solids. 

• Reversible flow: The pump can reverse its direction to clear blockages in the line.

• Accurate dosing: Offers very good repeatability (e.g., some models have ±0.5% or ±1% dosing accuracy). 

• Versatile control: Depending on model, it supports remote control via analog signals (e.g., 4–20 mA, 0–10 V), and can store multiple dosing programs.

• Compact & modular design: Some models are built for OEM integration, with quick-change tube cartridges to make maintenance easier. 

• Robust industrial build: Their larger hose-pump versions are rugged, built for continuous or intermittent duty, able to handle viscous, abrasive, or solid-laden fluids.

Example model:

• Verderflex Electric Peristaltic Dosing Pump — This is a self-priming peristaltic metering pump driven by electricity, able to dose fluids precisely.

• Verderflex Vantage 3000 P — A compact, programmable peristaltic tube pump designed for low-to-medium flow dosing, with high repeatability and options for remote control.
