液环真空泵

小气量，船用

气量10至75 ACFM（17至130 m3/h）

50多年来，NASH一直为船上起动灌注应用提供真空泵和成套设备，并继续为这个领域提供广泛的经典产品。这些泵紧密连接到船用电机，气量范围从10至75 ACFM（17至130 m3/h）。

描述

单级MD570、MD620、MHC和MHF系列可选择多种材料，包括青铜、铜镍和不锈钢。

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

 Nash起动阀的可行性和耐用性经过50多年证明，专门设计以用于真空泵启动系统。起动阀是一种适用于海上应用的浮阀。只要不存在液体，它具有从全部入口连接到真空出口连接的开放通道。当液体进入起动阀体时，浮力浮漂上升并关闭阀门。

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.
