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.
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
Klodpfsxv Ak Isx Ag Ujl
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

Watson Marlow 604S Peristaltic Pump
Watson Marlow604S
Call
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.
Klsdpfxsxv Ad Us Ag Uol
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.).
