As mentioned, peristaltic (hose) pump technology offers the design characteristics and method of operation to successfully handle wastewater that may have a high concentration of hard-to-contain and transfer chemicals. PSG®, Oakbrook Terrace, IL, USA, a Dover company, has been supporting operators in the wastewater market with its Abaque™ Series Peristaltic (Hose) Pumps, all of which have been engineered to defeat the challenges inherent in wastewater-handling applications.
The Abaque pumps excel in wastewater handling because they feature a seal-free design. This design ensures highly reliable product containment because it eliminates any potential leak or contamination points, while also allowing the pumps to run dry, self-prime and have low rates of product slip.
With regard to material compatibility, the pump’s hose – which is the only component that comes into contact with the pumped liquid – can be made out of a material that has been specifically designed to be compatible with the chemicals used to treat wastewater. Abaque offers three types of hose materials for its pumps:
- Natural rubber – highly resilient with excellent abrasion resistance and strength
- EPDM – has high chemical resistance, especially when handling concentrated acids and alcohols
- Buna® N – highly wear resistant to natural gas-containing products
The hoses used can also be selected based on their level of "fatigue resistance," or how the hose material is able to withstand stress and failure as the pump runs through its millions of pumping cycles. A hose that fails too soon will result in pump shutdown and, by extension, potentially prohibitive downtime, repair and replacement costs. Also, hoses that fail will leak their contents within the plant, which, again, can be a hazard for site personnel and the environment if harmful chemicals are being used.
Regarding particulate-handling, the Abaque pumps have been engineered to handle liquids with water-like viscosities up to those with a viscosity level as high as 70,000 cSt (352,000 SSU), solid particle sizes from 1.5 mm to 18 mm (0.06 inches to 0.71 inches) and soft particle sizes from 1.5 mm to 31 mm (0.06 inches to1.22 inches).
From a general operational standpoint, the Abaque pumps satisfy a wide range of wastewater-handling applications because the alternating contraction and relaxation of the hose within the pump casing enables it to produce a consistent rate of product displacement. This ability to maintain volumetric consistency makes the Abaque pumps ideal for strict the dosing of chemicals and 24/7 operating cycles that are common in wastewater applications.
Because of the diversity of material-compatibility concerns, importance of product containment and varying viscosity and particulate levels, the pumps used in wastewater-handling operations must be nimble and versatile enough to cope with a variety of operating conditions. Because of that, Abaque Series Peristaltic (Hose) Pumps have become a first-choice technology for plant operators who value highly reliable, safe, versatile and environmentally friendly pump operation.
