Portable Devices: Optimizing Diaphragm Pumps and Solenoid

It should be noted that too strong an emphasis to cut costs of the diaphragm pumps and solenoid valves could actually increase overall costs and decrease marketability of the device. For example, advanced, high-efficiency and high-reliability motor technology and solenoid valves significantly decrease power consumption—sometimes in half....<<more>>

How Equilibar Vacuum Regulators Work | Equilibar Precision

Vacuum Regulators, like Equilibar EVR series vacuum regulators, work by throttling flow between the vacuum pump and the process in order to control the process vacuum. This type, which is often referred to as a Vacuum Regulator, is actually a Back Pressure Regulator because the pressure controlled is at the inlet port....<<more>>
