Gardner Denver Thomas in Puchheim has an extension to the JADE series. In addition to the so-called 'angular' diaphragm for vacuum or pressure operations at high flow, a 'flat' diaphragm version is now available that can be used for pressure as well as vacuum operation. This new diaphragm is optimised for higher pressures rather than for higher flow.
The basis of this two-headed diaphragm pump model 1420 VDP remains the twin configuration of the pump heads. Perfectly balanced and due to the principal of the assistance provided by the second pump chamber at back pressure, the efficiency is increased by up to 90% compared with single-headed pumps. This unique energy balance results in a longer battery life.
In parallel operation the pump creates a final pressure of 1.9bar and 73% vacuum with a free flow of 6.3l/min. Depending on choice of motor the pump has the compact dimensions of 87mm to 112mm x 30mm x 75mm and a weight of 220g to 210g. At a sound level of less than 45dB(A) the 1420 VDP is extremely quiet with very low vibration.
Gardner Denver Thomas offers the pump with different motors – from low cost to high quality. The brushless motor version with integrated controller offers outstanding possibilities for flow control. The pump is available in 12V and 24V as well as with different eccentrics and materials for aggressive media.
Typical applications for the 1420 VDP are medical and analytic applications, pollution monitoring, fuel cells and battery-operated equipment.
