    Watson Marlow 323E Peristaltic Pump

    Watson Marlow 323E Peristaltic Pump

    Cambridge ID #: 18844

    Description:

    Peristaltic pumps are the simplest pump, with no valves, seals or glands to clog or corrode. The fluid contacts only the bore of a tube, eliminating the risk of the pump contaminating the fluid, or the fluid contaminating the pump. Peristaltic pumps can run dry. Peristaltic pumping is ideal for most fluids, including viscous, shear-sensitive, corrosive and abrasive fluids, and those containing suspended solids. They are especially useful for pumping operations where hygiene is important. Peristaltic pumps operate on the positive displacement principle. They are particularly suitable for metering, dosing and dispensing applications. Pumps are easy to install, simple to operate and inexpensive to maintain.

    Specifications:

    • Supply voltage/frequency: 100-120V/200-240V 50/60Hz 1ph
    • Maximum voltage fluctuation: ±10% of nominal voltage. A well regulated electrical mains supply is required along with cable connections conforming to the best practice of noise immunity
    • Power consumption: 100VA
    • Full load current: <0.43A at 230V; <0.86A at 115V
    • Operating temperature range: 4°C to 40°C, 40°F to 104°F
    • Storage temperature range: -40°C to 70°C, -40°F to 158°F
    • Maximum altitude: 2,000m, 6,560ft
    • Humidity (non-condensing): 80% up to 31C, 88F, decreasing linearly to 50% at 40C, 104F
    • Noise: <70dB(A) at 1m
