Used Watson-Marlow Watson Marlow 620 Du/R Peristaltic Pump for sale (73,145)

Condition: used, This listing is for the Watson Marlow 620 Du/R Peristaltic pump The unit is in full working condition and is ready for immediate use The 620DU is a process peristaltic pump (i.e. hose pump) designed for metering, dosing, and transfer of fluids. Because it is a peristaltic design, the fluid is contained entirely within the tubing, avoiding contact with internal moving parts (other than the tubing). It is suitable for remote control, automation, and integration into control systems (SCADA, factory logic, etc.). Wide control range & precision: The large turndown (2,650:1) gives flexibility to handle both very low and high flow rates with fine control. Remote / automation capabilities: Because it supports analog and digital interfaces, it’s well-suited for integrated systems. Pump protection & security: PIN locking helps avoid unintentional changes in process-critical applications. Low maintenance on non‑wetted parts: Since only the tubing contacts fluid, mechanical wear is mostly on the tubing, making part replacement simpler. Safe to run dry: Peristaltic pumps typically tolerate running dry without damage (unlike many positive displacement pumps). Reversible / ability to back‑flush: This is helpful when attempting to clear lines or avoid clogging. Limitations / Considerations Tubing wear / life: The hose or tubing is the consumable component. Chemical compatibility, pressure, and mechanical stress affect how often tubing needs replacement. Upper pressure / flow limit: While it handles decent pressure (~2 bar standard, possibly up to 4 bar variant), it’s not suited for very high-pressure pumping tasks. Nwodpfx Aaoxhdt Iszsl Enclosure limitations (non-“N” model): The standard 620DU is not fully sealed, so it may not be ideal for wet or harsh environments unless you use the “N” variant. Cost / complexity: More features, interfaces, and protection can make the system more complex (and costlier) to configure, install, and maintain.

Condition: used, This listing is for a Watson Marlow 520S Peristaltic Pump. Nsdpoxv A Uysfx Aazewl 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

Condition: used, This listing is for a Watson Marlow 604S Peristaltic Pump The unit is in full working condition and is ready for immediate release. The Watson‑Marlow 604S is a laboratory/industrial peristaltic (tube) pump, designed for dosing, metering, and fluid transfer tasks where the fluid must remain isolated from moving parts. It’s part of the “600” series of Watson‑Marlow pumps and is intended for relatively high flow rates in a controlled environment (e.g. labs, pilot plant, certain chemical or processing setups). Because it’s a peristaltic pump, the fluid only contacts the inner wall of a flexible tube, which makes it suitable for shear‑sensitive, corrosive or potentially particulated fluids, without contaminating the pump internals Strengths Clean & Isolated Flow: Because only the inner surface of the tubing contacts the fluid, there is no risk of cross‑contamination or fluid leaking into mechanical parts. Good Flow Capacity: With a relatively high maximum flow (≈ 11 L/min), it can handle moderate bulk transfer in addition to dosing. Nsdpexv Ad Ujfx Aazjwl Robust Housing: The IP55 rating makes it resistant to dust ingress and water spray, which is beneficial in industrial or lab environments with splashes. Variable speed control: The broad control range allows fine tuning of flow. Relative simplicity of maintenance: Replacing tubing is straightforward compared to more complicated pump mechanisms (valves, seals, diaphragms, etc.).

Condition: used, This listing is for 1 of 3 Watson Marlow 630S Peristaltic Pumps These units are in full working condition and ready for immediate use A peristaltic pump moves fluid through a flexible tube by sequentially compressing the tube (like a wave) which pushes the fluid forward. Because only the inner surface of the tube contacts the fluid, the pump mechanism is isolated from the fluid — this is useful for: Handling corrosive, abrasive or sterile fluids Avoiding contamination (the pump body doesn’t contact the fluid) Easy maintenance (replace the tubing rather than the pump’s internal components) Watson‑Marlow is a well-known maker of such pumps in lab, process, pharmaceutical, chemical, water treatment, and industrial settings. Typical applications / use cases Because of the flexibility, purity, and control of peristaltic pumps, the 630S is used in: Chemical dosing / metering (acid, base, reagents) Pharmaceutical / biotech processes Water / wastewater treatment Nwjdpjxhdtbjfx Aazel Food & beverage (for sterile or food-contact fluids) Laboratory and pilot-scale processing

Condition: used, This listing is for 1 of 2 Watson Marlow 530S Peristaltic Pumps The units are in full working condition and ready for immediate release. Overview & Function The Watson‑Marlow 530S is part of their 500 series cased peristaltic/process pumps. Nwsdpfx Aoxv Ak Ioazol Industrial Provider It’s used for precise fluid metering, dosing, or transfer in laboratory, industrial, pharmaceutical, food & beverage, water treatment, and other process environments. As a peristaltic pump, it works by compressing a flexible tube (or tubing element) with rollers or shoes, pushing fluid forward while the fluid never contacts moving mechanical parts (only the tubing). This gives isolation and reduces contamination risk Because fluid only contacts tubing, the risk of contamination or cross‑contamination is low, and maintenance is relatively straightforward (replace tubing / elements). Very good turndown ratio (i.e. ability to dial down flow finely) thanks to the wide speed control range. The user interface is designed for operational simplicity and clarity. Offers flexibility in control: it supports analog and digital remote control, SCADA integration, and bus communication.
