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. Ksdpfoxv Ak Iox Ah Ujnf 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. Ability to use different pumpheads and tubing materials to suit pressure, chemical compatibility, and flow requirement

Condition: used, This listing is for 1 of 2 Watson Marlow 504u Mk2 Peristaltic Pumps These units are in full working condition and ready for immediate release. The Watson‑Marlow 504U is a peristaltic (tube) pump designed for dosing, dispensing, or fluid transfer in laboratory, process, and industrial settings. Because of its design, the fluid only contacts the tubing, which helps with chemical compatibility, sterility, and ease of cleaning/maintenance. Knodpfexv Affex Ah Ujf It features a fairly durable, washdown‑resistant housing (IP55) in many versions, allowing it to tolerate exposure to splashing or low‑pressure water jets. A few variants (e.g., “Mk2” or “Du”) bring updates in control, enclosure, and durability Other features: The manual for the 504Du version describes that the pump’s speed control ratio is 220:1, giving a minimum speed of 1 rpm (for the 220 rpm drive) and 0.5 rpm (for 55 rpm version). The pump is intended to be installed on a horizontal surface with good ventilation and free airflow around it. The pump allows for remote control / automation through a 6‑pin port for auto/remote operation

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 Kedpfxexv Ad Ue Ah Uonf 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. 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.).
