Peristaltic Pumps

Peristaltic pumps are used wherever abrasive, viscous, or solids-laden fluids need to be pumped gently and reliably.

FLUX peristaltic pumps are self-priming positive-displacement pumps with flow rates up to 300 m³/h and pressures up to 10 bar. They require minimal maintenance, and the tubing can be replaced in just a few minutes without special tools.

Overview

FLUX peristaltic pumps handle abrasive, solids-laden, and highly viscous fluids up to 20,000 mPas, with flow rates up to 300 m³/h and pressures up to 10 bar. The fluid comes into contact only with the hose—no valves, impellers, or seals in the flow path. Nine sizes, ranging from FHP-10 to FHP-200, cover the entire performance spectrum.

Go to the product list

Wastewater and Sewage Treatment Works

Pumping wastewater and leachate—self-priming, solids-tolerant, dry-run-safe.

Agriculture and Biogas

Slurry, feed, and fermentation residues—even with high dry matter content (up to 25%) and high solids content.

Mining and Civil Engineering

Drilling mud, oil sludge, and abrasive suspensions—high wear resistance thanks to NRH hoses.

Food Processing

Food scraps and slaughterhouse waste—gentle conveyance; FDA-compliant hoses available.

Chemical Industry

Aggressive and high-viscosity fluids up to 20,000 mPas – EPDM hoses for concentrated acids and alkalis.

Oil and Gas Industry

Oil sludge, used oil, and cooling lubricants – cutting oil extraction, suitable for onshore and offshore use.

Biogas & Agricultural Industry

Reliably pumps liquid manure, solid manure, corn, and food waste. The FLUX peristaltic pump is designed for slurry-like and solids-laden media. Its robust construction reduces wear and significantly lowers maintenance requirements.

Knowledge and Technology

Selecting the right peristaltic pump depends on the fluid, the solids content, and the required flow rate. The following sections explain the operating principle, the hose materials, and a comparison of the available sizes.

Function and Design of FLUX Peristaltic Pumps 

The FLUX peristaltic pump operates as a self-priming rotary positive-displacement pump. A rotor with two opposing POM rollers squeezes a flexible hose, thereby generating the flow. The fluid comes into contact only with the hose—there are no valves, impellers, or seals in the flow path.

Since the flow rate depends solely on speed and pump size—not on viscosity or solids content—the throughput can be precisely controlled via a variable-frequency drive. 

Hose material, pump head, and drive can be combined

Nine sizes, ranging from FHP-10 to FHP-200, cover flow rates from 330 l/h to 300 m³/h.

  • Self-priming & dry-run protection: No priming required, safe dry-run operation—ready for immediate use
  • Gentle pumping: Low-shear displacement—media structure remains intact
  • Low-maintenance: Hose is the only wear part; replacement takes minutes without special tools
  • Performance specifications: Up to 300 m³/h, up to 10 bar, up to 20,000 mPas

How does the roller principle work?

The roller principle is the basis of the FLUX hose pump: A rotor with two opposing rollers rotates inside the housing, sequentially compressing the flexible hose.

  1. As the rotor rotates, the first roller comes into contact with the hose and compresses it. This compression creates a separation between the suction and discharge sides
  2. A vacuum is created on the suction side, which draws in the fluid. As soon as the second roller compresses the hose, a hermetically sealed chamber is formed between the two rollers. As the rotor rotates, the fluid is conveyed through this specific chamber toward the outlet. The rollers move along the hose, pushing the fluid inside the hose toward the outlet.
  3. When the roller is released from the hose, the hose relaxes, returns to its original shape, and the fluid is discharged on the discharge side. This cycle repeats continuously, thereby conveying the fluid.
