Piston vacuum pump

lubricatedtwo-stage

Create a strong vacuum with these one and two-stage pumps. Operating under quiet conditions, these high-powered vacuum pumps are designed to not disturb workers. The devices can be used in various applications such as air or gas sampling, pressure vacuum filtration, precious metal recovery, process control, and pneumatic controls. The powered and non-powered vacuum pumps available are extremely flexible to be compatible with pre-existing instruments. Sturdy Hand Pump Features Hose Connectors For Vacuum And Pressure Sturdy Hand Pump Features Hose Connectors For Vacuum And PressureThis solidly constructed air pump has an enameled steel barrel, plated steel valve hardware, and a wooden handle. The molded rubber piston has a triple O-ring seal, and both the inlet and exhaust ports are equipped with 9mm plain hose connectors. This allows the pump to be used with standard thick-wall tubing for vacuum experiments and also to generate overpressure. Dimensions: Length is 35cm, barrel diameter is 2.5cm, length of stroke is 19cm. Displacement is 66ml/stroke. Hose connectors are 9mm o.d., 22mm long. Efficient combination of a pump and a vacuum plate. • Plate features a silicon seal, which allows perfect sealing of the bell jar with the plate • 20 cm diameter size Just a few strokes of the pump are enough to establish a vacuum in a bell jar, so students can observe the reducing sound level of the bell. The plate can also be used with electric vacuum pumps with the help of a three-way stopcock under the plate.
