This listing is for 1 of 2 Watson Marlow 520S Peristaltic Pump. The unit is in full working conditi (more)on and is ready for immidate realese. 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 microliters/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

KNF IP65 FEM 1.02 TT.18S Liquid Pump KNF SIMDOS diaphragm pumps offer a variety of options to suit m (more)ost laboratory liquid metering and dosing needs. The FEM 1.02 TT.18S version has a liquid transfer flow rate of 0.03 – 200 mL/min and discreet dosing volumes of 0.03 – 999 mL. It is constructed with the following chemically-resistant flow path materials: PVDF head, PTFE covered diaphragm, and FFKM valves. The easy-to-read display combined with a touch control knob makes programming and access of all functions very intuitive. All SIMDOS pumps are simple and intuitive to operate, compact, and quiet, making them a welcome addition to any business or academic lab. They are effective against pressures of up to 85 psig and transfer viscous media up to 500 centistokes (reduced flow rate above 150 cSt). The integrated software permits the transfer parameters to be modified for a range of different viscosities at the touch of a button. With a durable and IP65 splash-proof design, these pumps are maintenance free, and provide trouble-free ±2% accuracy and ±1% repeatability performance. SIMDOS 02 pumps are self-priming up to 6.6 feet of water, and can run dry indefinitely without damage. Also, unlike peristaltic pumps, there are no troublesome tubing to break or fatigue.INCLUDED: The KNF IP65 FEM 1.02 TT.18S Liquid Pump includes: - Power Cord - Operator's Guide - Manufacturer's Documentation - 1 Year Manufacturer's Warranty

Heidolph Hei-FLOW Expert 600 Peristaltic Pump This model has a flow rate of 2.0 — 4,056 ml/min and i (more)s designed for operation with single-channel pump heads. The analog interface makes it possible that all functions can be controlled externally. A control accuracy of ±3.5% and a conveyor speed of 24 to 600 rpm provide optimum process conditions. In addition, sensitive media can be protected from influence by using the optional foot switch. Like all Heidolph peristaltic pumps, the conveying direction of this model can be changed by a simple push of a button. Furthermore, the accelerated filling and emptying of the tubing is simplified, since here only the button for the maximum speed has to be pressed.
