The J-Series (Macro) Dia‐Vac® normally runs at 130° to 150° F. It is not an indication of trouble if either the outer surface of the pump or motor are hot to the touch. The motor is specifically designed for use in an environment ranging in temperature between ambient and 104° F. For temperatures above 104° F please contact the factory to discuss available options such as the elevated head. It will eventually fail or overload if exposed to temperatures in excess of its normal operating conditions.
Qualified personnel must perform all work to assemble, install, operate, maintain and repair the pump/air motor assembly.
Using air as the power source, the pump is designed to compress gas products only. The pump is not designed to compress liquids. The pump is designed to create flow of a gaseous product and may generate a vacuum at the inlet and/or pressure at the outlet. It can be supplied as a single head or a double head unit. The double head unit can be plumbed (connected) in parallel or series. In a parallel connection, both inlet ports are connected together and both outlet ports are connected together to form the inlet and outlet of the pump. In a series connection, the outlet port of the first head is connected to the inlet port of the second head. The pump inlet is the inlet port of the first head and the pump outlet is the outlet port of the second head. Continue reading →
Hello, everyone. My name is Chris, and welcome to our YouTube channel.
Today we’re going to be going over how to change a diaphragm on one of our Micro Dia-Vac diaphragm pumps. When changing out a diaphragm, it’s
typically done because the pump is starting to get a little bit of low
performance and maybe low pressure, low flow. Or some people they just want
to service the diaphragm at regular intervals. Whether that’s six months or
a year, it really just depends on the application.
