液環真空泵

小氣量，船用

氣量10至75 ACFM（17至130 m3/h）

50多年來，NASH一直為船上起動灌注應用提供真空泵和成套設備，并繼續為這個領域提供廣泛的經典產品。這些泵緊密連接到船用電機，氣量范圍從10至75 ACFM（17至130 m3/h）。

描述

單級MD570、MD620、MHC和MHF系列可選擇多種材料，包括青銅、銅鎳和不銹鋼。

 如需更高的真空度，雙級AT34和AT64泵的容量范圍為40至75 ACFM（70至130 m3/ h）。

 Nash起動閥的可行性和耐用性經過50多年證明，專門設計以用于真空泵啟動系統。起動閥是一種適用于海上應用的浮閥。只要不存在液體，它具有從全部入口連接到真空出口連接的開放通道。當液體進入起動閥體時，浮力浮漂上升并關閉閥門。

Liquid Ring Vacuum Pump

Small Capacity, Marine Duty

Capacity 10 to 75 ACFM (17 to 130 m3/h)

NASH has been providing vacuum pumps and packages in shipboard priming applications for over 50 years and continues to offer a wide range of classic products for this service. These pumps are provided close coupled to a marine duty motor have capacities ranging from 10 to 75 ACFM (17 to 130m3/h).

The single stage MD570, MD620, MHC, and MHF series are available in a variety of materials including bronze, copper, nickel, and stainless steel.

If deeper vacuum is required, the two stage AT34 & AT64 pumps are available with capacities ranging from 40 to 75 ACFM (70 to 130 m3/h).

Proven to be dependable and durable for over 50 years, Nash’s priming valves are designed specifically to be used in vacuum pump priming systems. The priming valve is a float valve ideal for marine applications. It has an open passage from all inlet connections through to the vacuum outlet connection as long as no liquid is present. When liquid enters the priming valve body, the buoyant float rises and closes the valve.
