Used WELCH 1400 #109949 for sale

WELCH 1400 direct-drive rotary piston pump is commonly known as a low-vacuum-pressure pump, ideal for use in a variety of applications. This pump is a single-stage piston pump capable of creating a nominal 15Torr vacuum and is driven by a 1/2 hp, 115/230 V, 60 Hz motor. It includes a gas ballast to reduce condensation, a vacuum relief valve to prevent over-pressurizing the vessel, and a 3/4'' intake and a 1/4'' exhaust port for ease of connection to external systems. 1400 pump is designed with a single-stage pumping action, which reduces wear on the piston and allows for more efficient operation. The piston is specifically designed to react quickly to changes in pressure, allowing the pump to respond rapidly to changing conditions. The improved efficiency of the piston reduces the need to recondition seals, which leads to longer-lasting operation. The direct-drive design also helps to reduce service times, as the piston is designed to continue running even when the pressure changes. WELCH 1400 is designed with a 3-in-1 filter to help protect the internal components from harmful contaminants. This filter is critical to protecting the piston from particles or other debris that could damage the internal components, resulting in decreased reliability and efficiency . Additionally, the inlet and exhaust ports can be used to connect 1400 pump to an auxiliary condenser, enabling an extended vacuum pressure. This multi-phase connection provides a closed loop for degassing, helping to reduce contamination and improve the efficiency of the pump. WELCH 1400 pump is designed for easy use and reliable operation even in difficult environmental conditions. Its included gas ballast helps reduce the risk of condensation forming in the pump's interior, while its inlet and exhaust ports offer added flexibility for connecting to external systems. The piston is optimally designed to react quickly to changes in pressure while still providing robust performance and durability. Finally, its integral filter helps keep the internal components free from contaminants, which can lead to decreased performance. As a result, 1400 direct-drive rotary piston pump is a reliable, long-lasting solution suited for a variety of low-vacuum-pressure applications.
