Used ULVAC D650D #9287376 for sale

ULVAC D650D is a dry diaphragm mechanical pump designed for high vacuum applications. The unique oscillation diaphragm design allows for efficient operation at both high and low pressure ranges. It is a manual pump, which comes in two sizes: D650DL and D650D-S, both of which have a pumping speed of 20 m3/h. The pump is composed of two main parts: a diaphragm and a drive unit. The diaphragm is made of medical-grade silicone and nylon and is designed to be durable and airtight. The drive unit includes a motor-driven drive shaft, which allows the diaphragm to vibrate and facilitate air leakage. The motor is powered by either a 220-240V AC power supply or a 12V DC power source. Additionally, the pump is equipped with a 0-150 psi (0-10 bar) pressure regulator and a gauge for accurate readings. ULVAC D650D has an suction capacity of up to 200 Torr, exhaust pressure of up to 175 Torr, and flow rates of up to 20 m3/h. Depending on the type of application, the pump can be used for either single-stage or multi-stage evacuation. In single-stage mode, the pump operates at a continuous pressure of up to 126 Torr and in multi-stage mode it can reach up to 3000 Torr. The pump features an oil-free design and a noise level of only 34 dB(A) at the working pressure of 8 Torr. The high performance and low noise level make D650D an ideal choice for applications such as vacuum ovens, glove boxes, ultra-high vacuum systems, and other high-vacuum research instruments. The pump is fitted with a CFC-free cooling system and has a total isolation of 350 kV. Additionally, the pump also comes with an LED indicator for protection against over-heating or over-current. The compact design and light weight of 9.5kg make ULVAC D650D easy to transport as required. In conclusion, D650D is a great option for those looking for a reliable and efficient dry diaphragm pump for high vacuum applications. Its unique design and various features make it a great choice for both industrial and research uses.
