    Testing

    The Welch 1405 is used and reconditioned. Our technicians use essential tools like a vacuum gauge, leak detector, and proper vacuum pump oil to ensure effective testing. During the process, we inspect connections, check oil levels, monitor vacuum performance, and detect leaks to assess the pump’s condition accurately.

    The listed specifications come directly from the manufacturer, but a vacuum pump’s suction naturally degrades over time. So, after receiving your order, we will test the pump and inform you of its actual vacuum pressure. We remove oil from all rotary vane vacuum pumps prior to shipping. You will need to acquire the proper oil and fill the pump upon arrival.
