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.
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.
