The Leybold Trivac S25B and D25B are strong, reliable pumps. They are two-stage rotary vane pumps. People use them in many places. Labs, coating systems, heat treatment, freeze drying, and many other industrial applications.
The D25B is a dual-stage pump. The number “25” in the type designation indicates the pumping speed in cubic meters per hour. At 60 Hz, the D25B pumps about 30 cubic meters per hour.
The pump has a built-in oil pump for force-lubrication of the bearings. It has an internal demister to separate oil from gas. The oil-level glass has prisms so you can see the oil level easily. The pump module can be easily removed without special tools.
