Watson Marlow 504S Peristaltic pump easy load drive head MKII IP55

Watson Marlow 504S Peristaltic pump easy load drive head (Double Tube) MKII IP55 220rmp 100-120/220-240V Condition is used 𧪠Watson-Marlow 504S Peristaltic Pump â Detailed Product Description The Watson-Marlow 504S peristaltic pump is a precision-engineered solution designed to handle a wide range of fluid transfer applications. Built with versatility, durability, and hygiene in mind, this pump is a cornerstone in laboratories, pharmaceutical production, food processing, and industrial automation. ð Advanced Functional Design Peristaltic Pumping Principle Utilizes a rotating roller assembly within a circular pumphead (commonly the 501RL or similar), which compresses flexible tubing against a track. This creates a series of occlusions that move fluid forward with high precision and without any direct contact between the fluid and the pumpâs mechanical components. Closed-Fluid Path Since fluids only contact the tubing, the risk of contamination is virtually eliminated. This makes the 504S perfect for sterile environments or when handling corrosive or hazardous fluids. Reversible Flow Direction The motor supports bidirectional operation, enabling both filling and emptying applications, as well as backflushing if needed. âï¸ Control and Performance Features Speed Control Manual variable speed control allows operators to precisely adjust flow rates from 0.5 to 170 RPM. Optional digital or analog control modules may be available depending on the specific unit configuration. Flow Accuracy and Repeatability Offers a repeatability rate of ±0.5%, ideal for applications requiring consistent dosing and dispensing. Low Shear Pumping Gentle pumping action makes it suitable for shear-sensitive fluids, including cell cultures, suspensions, or protein solutions. Self-Priming Capability Can self-prime up to 8 meters vertically, significantly reducing setup time and simplifying system integration. Dry Running Tolerance Safe to run dry without damage to the pump or tubing, further enhancing its durability in varied operational settings. ð ï¸ Construction and Build Quality Rugged Enclosure The pump features a powder-coated steel housing that resists corrosion and physical wear, suitable for demanding environments. Maintenance-Free Drive The motor and gearing are sealed and require no lubrication or scheduled service, resulting in minimal downtime. Quick-Change Pumphead Tool-free tube loading system allows for rapid tube replacement, reducing maintenance time and increasing throughput. ð Technical Specifications Drive Type : Synchronous AC motor Pumphead Compatibility : 501RL, 520R series, and others with proper mounting Speed Range : 0.5 â 170 RPM Flow Range : Up to ~2.0 liters per minute (depending on tube size) Voltage : Typically 230V or 110V AC (custom units may support 12V DC) Dimensions : 27 cm (W) x 34 cm (D) x 13 cm (H) Weight : Approx. 8â9 kg Enclosure Rating : IP31 (protection from small tools and wires, and limited moisture) Operating Temperature : 5°C to 40°C Noise Level : <60 dBA at 1 meter 𧩠Applications Biotechnology : Media transfer, buffer solutions, and fermentation sampling Pharmaceutical : Accurate volumetric dosing, cleanroom transfers Water Treatment : Chemical dosing of flocculants, pH adjusters, and disinfectants Food & Beverage : Flavors, colorants, and ingredient delivery without contamination General Industry : Ink transfer, adhesives, resins, and lubricants â Summary The Watson-Marlow 504S is a powerhouse peristaltic pump offering unparalleled precision, cleanliness, and versatility. With its low-maintenance design, precise flow control, and robust construction, itâs an ideal choice for users who demand reliability in critical fluid handling tasks.
