Thermo Fisher Scientific has developed the Masterflex P/S line of digital peristaltic pumping systems.
The P/S line is a wide range of complete systems, which include either a standard digital drive, a computerised drive or a stainless steel NEMA 4X process drive.
The P/S pumping system features a small footprint, plus the units are stackable, making them especially well-suited for limited-space clean room and laboratory applications.
The Masterflex P/S digital pump provides a number of important advantages for the laboratory user, including repeatability of 0.1 per cent to maximise productivity in precision liquid dosing, batch dispensing and filling applications.
A turndown ratio upwards of 6,000:1 provides users with flexibility in volume and time of dispense in addition to a smooth, seamless operation and an extremely broad flow range in a single tubing size.
With flow capacities from 0 to 54 gallons per hour, a flow range of 380,000:1 can be achieved in one pump head.
P/S pump systems are available as a complete system with Masterflex Easy-Load 2 or high-performance pump heads.
The pumps are self-priming, able to operate dry and suitable for most chemicals, and contain no valves or seals to replace.
Fluid only contacts the tubing, providing for contamination-free pumping and easy CIP/SIP.
A special feature of the Masterflex P/S pumping system is a multi-language, intuitive, man/machine interface with four-line graphical LCD display providing direct readout of pump speed (rev/min), flow rate (ml/min), three dispensing modes and menu options.
For the operator, an easy-to-use keypad eliminates set-point overshoot and provides easy navigation that includes a number of on-screen programming features and a wide range configurable remote-control capability, including RS232 and USB connectivity.
The brushless, no-maintenance drives have built-in diagnostics for improved reliability.
Combined with its bidirectional flow and self-priming capabilities, high turndown, superior accuracy, and intuitive interface, this makes P/S pump systems suitable for virtually all applications where precise, repeatable flow control is required.
