Dual Diaphragm Vacuum Pump w/24V DC Motor+Controller Anti-Vibration KNF N813.3. Dual diaphragm vacuum pump units made by KNF Neuberger in the USA. These are the same dual pumps in another of our listings but they are attached to a 2 stage vibration isolation mount.
The mount alone tips the scales at 9 pounds and have 2 layers with large and small rubber isolators to damp both low and high frequency vibration. The overall dimensions of the mount are 230 x 143 x 55mm. This significantly reduces the noise and vibration of the pump, especially when run at full speed.These pumps are powered by a 3 phase brushless DC motor. They feature a built-in, adjustable-speed motor controller that is powered by 24V DC and has remote start and speed inputs as well as a tachometer output. We have bench tested each of these units. We configure the motor controller to auto-start when power is applied and to use the on-board trimpot for speed control. You can turn the trimpot clockwise to reduce the motor speed which will reduce the noise, vibration and also the flow rate. These are configured with 2 independent pumps.
Each inlet port has a manual valve and a quick release fitting for 5/32 OD tubing. The outlets have a silencer installed for quiet operation.
It is possible to reverse the ports and use this for pressure rather than vacuum or plumb the pumps in series / parallel for higher flow / vacuum. The black pump bodies can be removed and re-installed rotated by 90 or 180 degrees to facilitate tubing routing.Note that the inlet and outlet ports have G 1/8 threads. Forcing a tapered NPT threaded fitting may break the plastic pump housing. These are an OEM version of a KNF model N 813.3 AN.
