Peristaltic pumphead is advanced yet cost-effective
Watson-Marlow Pumps Group is launching a new easy-loading yet rugged low-flow pumphead. Known as the 114 pumphead, the competitive priced new product is described as "smart, safe and small."
Designers at Watson-Marlow Alitea have created the innovative 114 in response to calls for an advanced yet cost-effective low-flow pumphead in a compact configuration. It therefore complements Watson-Marlow's existing and popular 313 pumphead, which has sold in hundreds of thousands for applications ranging from milk shake vending to medical equipment and machinery.
The smart new 114 is stylish and modern; its 'flip top' design is both attractive and functional. For extra pumphead longevity, strong and high-performance materials provide resistance to chemicals and detergents, as well as very good temperature stability, while fixings and ball bearings are manufactured from high-grade stainless steel. Additionally, gentle tube handling ensures tube life is maximised at all times.
Fit and forget
Inherent safety features mean that no operator adjustments are necessary, resulting in long-term robust and trouble-free running. Flow rates up to 340ml/min can be achieved at 400rpm using 4.8mm bore tube. The pumphead features a universal drive connection that suits 6-10mm drive shafts. Rotor movement can be viewed through windows in the front of the unit as an additional safety measure, while other features such as custom colours, a logic off-switch and rotation sensor can be fitted, providing additional layers of safety as required.
Simple to fit and small in size, the 114 is suitable for multiple individual pumphead installations. The single-channel 114 measures just 64 x 64 x 41mm yet it features a host of functions normally associated with larger and more expensive pumpheads. For instance, it offers four rollers for reduced pulsation, and spring-loaded tube holders with automatic tube stretching for high accuracy, and repetitive flow and pressure performance. Moreover, operation is entirely intuitive, hence no experience or training is necessary. For example, tubing can be loaded easily using one hand, in a matter of seconds.
The 114 will have universal appeal across a range of sectors that includes medical device manufacturers. Here, dental, surgical and dialysis equipment OEMs are set to be the chief beneficiaries. Other industries targeted by Watson-Marlow include: biotech, pharmaceutical and instrumentation (fermentation/bioreactor control equipment, clinical diagnostic instruments, dosing reagent machines); chemical (water analysis equipment, TOC analysers, dosing machinery); and food (vending machines, dispensing equipment). With all of these sectors demanding high levels of hygiene, attention has been paid to design details to ensure the 114 pumphead is easy to clean and free of potential dirt traps.
