Swing-Piston Pump Comes In Compressor Or Vacuum Pump Models
KNF announced its newest addition to its OEM swing-piston pump line, the NPK04. The NPK04 is ideal for use as a transfer pump, is available in compressor or vacuum pump models and can be operated in any position. Its sealed, swing piston moves media oil-free and without adding contamination. Despite its size, it features 3.3 liters per minute of free flow, and is available in an optimized version for vacuum (max. 21.6 in. Hg) or pressure (max 31 psig) generation. Two motor options include standard DC or an economical brushless-dc motor.
The BLDC model is only 2.5 in. long, is available with optional logic speed control interface and features low EMI/RFI. The pump is maintenance-free, very quiet, and exhibits low vibration, low current and power consumption, making it ideal for mobile, battery-powered applications. All standard KNF pumps can be customized to meet specific OEM performance requirements. It is suitable for use in medical and analytical instruments, ink-jet printers, and pneumatic supply functions for prosthetic devices and ergonomic furniture.
Compact Vacuum Pumps Suit Single & Multiple Filtrations
Vacuum filtration is one of the most common applications used for sample preparation in chemistry, microbiology, waste water control and other analytical processes. The new VACUUBRAND ME1 and ME1C diaphragm pumps offer a compact, high performance and easy to-use solution which is perfect for both single and multiple filtrations. These new pumps deliver pumping speeds of 14lpm and ultimate vacuum of 100mbar. They provide a well-proven and extraordinary long diaphragm life (10,000-15,000 operating hours), whisper quiet operation and low vibration. The functional, space saving and innovative design with readily accessible top mounted power switch ensures convenient and quick operation.
Both models feature robust PTFE diaphragms and valves for optimal chemical resistance. The ME1C features a full fluoropolymer flowpath, for a complete chemistry-design pump. An optional vent control valve with dial gauge enables variable fine adjustment of the pumping speed.
Diaphragm Vacuum Pump Is Compact & Cool-Running
KNF N860 Series diaphragm vacuum pumps introduced solutions to sample, transfer, or evacuate air and gases. These compact and cool-running pumps have a patented structured diaphragm promoting optimized pneumatic performance and long service life. The pumps can suit a wide variety of process, laboratory, or OEM applications ranging from large-scale rotary evaporators and continuous/manifold filtration systems to process control sampling. Customization capabilities expand their application potential to many other areas.
These pumps feature as standard specially engineered multi-port valves to tolerate condensation without damage, perform oil-free transfer with uncontaminated flow and minimal maintenance, and run quietly with low vibration. They can achieve enhanced gas tightness with leak rates as low as 6 x 10-3 mbar L/s, deep vacuum potential of 2 mbar, and flows as high as 110 L/min.
Their modular design and available options enable easy customization to tailor pump to application. Pumps can be equipped with standard AC motors or explosion-proof AC versions for compliance with Class 1, Division 1, Groups C & D hazardous locations. Single- or doubled-headed pump options can also be specified. Wetted material choices range from economical aluminum heads and EPDM diaphragms to solid glass-filled PTFE heads and PTFE diaphragms, which offer higher resistance to corrosion and chemicals.
All N860 Series pumps are engineered to start reliably against vacuum, mount and operate in any installed position, and can be easily serviced in the field.
Vacuum Pump System Controler Has Touchscreen
The VacTrac(TM) Series 24/128 Controller features enhanced graphics and control of up to 24 vacuum conveying pumps, 128 loading stations and 128 purge valves. The 24/128 controller utilizes a DeviceNet distributed I/O network, with standard features that include an Allen-Bradley CompactLogix controller with 10″ color touch-screen operator interface.
Easy to follow graphical touch-screens provide total navigational control of the central vacuum system. The setup screen, for example, allows for the naming of loading stations, pumps, purge valves and material sources so you know exactly what is in each hopper and where it is located.
Manifold sharing capabilities allow the 24/128 to reduce the cost for tubing and purge valves and can stage and sequence six vacuum pumps per manifold line. The 24/128 can assign each loading station to any of the pumps connected to the same manifold. When a loader senses demand, the controller triggers the assigned pump to convey. If more than one loader on the manifold needs material simultaneously from different pumps, the controller’s manifold sharing function will then stage the pumps so that they can use the same manifold. The first pump will begin, and when its demand is filled, the next pump will be triggered. The result is a flexible system with minimal tubing and purge valves.
The touchscreen display provides an icon based platform for easy maintenance, operation and troubleshooting. Easy to read diagnostics, operation and installation instructions as well as spare parts information are all available from the touch screen.
KNF Diaphragm Dosing Pumps for Liquids
New KNF diaphragm dosing pumps for liquids (Types FEM 1.02 and FEM 1.09) introduce ideal solutions delivering superior accuracy and repeatability over a long service life. These compact pumps integrate simple 2-phase stepper motors engineered for optimized levels of controllability and cost efficiency. An optional and adaptable control module easily integrated into any system can expand control potential to suit particular application requirements.
Typical applications include medical diagnostics, industrial dosing systems, fuel cells, semiconductor processing, and wafer analysis, among others.
The FEM 1.02 pump achieves flow rates from 0.2 ml/min to 20 ml/min and FEM 1.09 pump from 0.9 ml/min to 90 ml/min. Both versions are small (62mm x 75mm x 63mm), cover a wide dosing range (1:100), operate oil-free with virtually no maintenance, and can serve reliably for more than 10,000 hours.
Among other features, these pumps are self-priming to 8.5 in.Hg, demonstrate consistency over time (1% repeatability), and exhibit excellent leak-tightness and chemical resistance. An innovative valve system minimizes head volume by ensuring that air cannot collect inside the pump head. Depending on pump version, head materials include polypropylene (PP) or PVDF and internal elastomeric components are manufactured from EPDM, FFPM, and PTFE. Pumps are both easy to operate and to adjust. Ports are available in UNF ¼-28 or compression fittings.
Modular pump design offers OEMs the versatility to choose from a wide variety of standard materials, voltages, frequencies, accessories, and options to satisfy application demands.
