Peristaltic Dosing Pumps from Kelair Pumps Australia

Cutting costs without compromising on quality

During a routine site visit by Kelair staff to a leading Australian paper mill, our customer sought a pump recommendation for a polymer dosing application. While the customer was satisfied with the hydraulic performance of their positive displacement pumps, they were concerned about the high cost and the operational impact of maintenance down-time. The customer's operations used a progressive cavity type of positive displacement pump. These pumps are notoriously dry-run sensitive and as a result, without sufficient lubrication, parts deteriorate rapidly. The replacement of affected parts, such as the pump's stator or rotor, can be time consuming and relatively expensive.

Kelair Pumps recommended a pump from the Albin range of peristaltic dosing pumps. These pumps are characteristically easy to operate and simply constructed. They have no shaft seals, valves, lobes, immersed rotors or vanes, which minimises product loss, blockages and part replacement. There are no mechanical parts in the pumped product stream limiting any chemical compatibility concerns to the hose, which is a low-cost, low-maintenance, and easily serviceable component

The peristaltic pump can be fitted with hoses to suit a wide hydraulic coverage. Hoses are also available in a range of materials with braided nylon reinforcement or chemically resistant tube lining to support broad chemical coverage, from abrasive to viscous fluids.

Peristaltic hose pumps have a self-priming capability and can be operated from dry-run without damage to the casings or the pump providing continuous service with limited interruption for operational maintenance and hose replacement.

The Albin peristaltic pumps also have exceptionally low shear. The gentle, low pulsation pump action is ideal for shear sensitive products, such as polymers, to safeguard product quality and consistency.

Peristaltic pumps have no backflow or slip, creating a consistent flow directly proportional to the rotation speed with dosing accuracies of ±1%. Some hoses types may create a noticeable pulsation in the system but this can be simply eliminated by a pulsation dampener.

Kelair Pumps strongly recommends the Albin peristaltic pumps for consistency, reliability, low maintenance and reduced down-time. Key features to bring confidence to any pumping process are:

- Durable, low maintenance and simple pump construction.
- Accurate and repeatable dosing and metering.
- Self-priming, reversible operation and continuous dry-run capability.
- Hose parts low-cost and easily serviceable.
- Hose compatibility to chemicals, flow rates, viscosity and texture of fluids.

Our paper mill customer has since installed the Albin peristaltic pump and is unconditionally satisfied with its performance. They intend to order more units in the future to guarantee the highest quality and operational safety in the polymer dosing process.
