What are the main advantages of a peristaltic pump?

Peristaltic pumps offer contamination-free pumping as the fluid only contacts the tubing. They can handle a wide range of fluids, including viscous, shear-sensitive, and corrosive materials, and can run dry without damage.

Can this pump be used for continuous operation?

Yes, peristaltic pumps like the 520S are designed for both continuous pumping and precise dispensing applications. The duty cycle will depend on the specific application and tubing life.

What type of tubing is compatible with this model?

This model typically uses specific tubing sizes and materials designed for peristaltic pumps. Buyers should consult the manufacturer's specifications or the seller for compatible tubing types and bore sizes.

Is this unit suitable for sterile applications?

Due to the fluid only contacting the tubing, peristaltic pumps are well-suited for sterile applications, provided appropriate sterile tubing and aseptic techniques are used.

Does this pump come with a pumphead?

Peristaltic pump listings often include the drive unit and may or may not include a pumphead. Buyers should confirm with the seller whether a pumphead is included with this specific unit.

This listing is for a Watson Marlow 520S Peristaltic Pump. (1 of 7 Available)

The unit is in full working condition and is ready for immediate release.

Peristaltic pumps are the simplest possible 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 operate dry without risk.

Easy to install, simple to operate and inexpensive to maintain, peristaltic pumps are ideal for most fluids, including viscous, shear-sensitive, corrosive and abrasive fluids, and those containing suspended solids. Suitable for metering, dosing and dispensing applications.

520S drive offers manual control via a large-key membrane keypad: speed adjustment; run and stop; forward/reverse; "Max" key for rapid priming and purging.

Supply voltage/frequency: 100-120V/200-240V 50/60Hz

Flow rates from 4 micro-litres/min up to 2.4 liter/min

Precise 2,200:1 speed control range from 0.1 to 220 rpm in 0.1 rpm increments

Large speed/flow display and easy to use tactile membrane keypad. Incorporates keypad lock

Manual control and flow rate calibration

MemoDose for accurate single shot dispensing

Sterile fluid transfer in pharmaceutical and biotech manufacturing.

Typical Specifications

Typical flow rate range: For this class of equipment, flow rates commonly range from microlitres per minute up to several litres per minute, depending on the pumphead and tubing size.
Speed control: Units of this type typically offer a wide speed control range, often with fine increments for precise flow adjustment.
Power supply: Commonly found with universal voltage input, such as 100-240V AC, 50/60Hz, allowing for global compatibility.
Control interface: Typically features a membrane keypad for manual control, including speed, direction, and start/stop functions.
Fluid contact materials: Only the tubing contacts the fluid, with various tubing materials available to suit different chemical compatibilities and application requirements.
Maintenance: Maintenance is generally low, primarily involving periodic replacement of the pump tubing.
