Used WELCH 1402 #9037018 for sale

WELCH 1402 Pump is a laboratory-grade rotary vane pump that is designed for sample preparation tasks in a variety of industrial uses. This single-stage, oil-sealed mechanical pump is capable of achieving oil-free operation through the use of a built-in oil mist eliminator. This eliminates problems associated with both the intake and exhaust of contaminants from the pumped stream. The design of 1402 makes it ideal for pumping of samples with varying vapor pressures. It can pressurize samples up to 10 psi above atmospheric pressure and 34 psi above atmospheric pressure without surging or cavitation. Furthermore, the ability to use either dual start-stop switches or Network connections make for improved safety features as well as better integration with complex systems. WELCH 1402 offers low-pulsation pumping and durability for continuous use without requiring periodic maintenance. Its vacuum range is 0.05 to 0.35 Torr, ultimate pressure is 1.3 x 10-2 Torr and compression ration is 47.7:1. It has a displacement rate of 10 liters per minute at 60Hz (US) or 8.5 liters per minute at 50Hz (international) with an inlet connection of 90mm ISO160 nozzle on the fore pump. The pump itself is equipped with a cooling fan which extends its working life and prevents overheating. Furthermore, the motor can be ordered in either 220 or 230 Volt versions. 1402 also uses external filtration for longer life and improved maintenance. Additionally, the motor has an adjustable speed drive which allows manual control of the pumping rate, up to 200ml per minute, for minimizing imbalancing when processing multiple samples. WELCH 1402 Pump is a dependable and reliable unit that is designed to take on the most demanding applications. It is a durable, reliable and safe pump that can handle the toughest of tasks while protecting against potential hazards. Furthermore, its modern design and ease of use make it perfect for use in both laboratory and industrial environments.
