Operation Principles of LMI Solenoid Pump LMI Pumps

For instance, the LMI PD series can achieve up to 2.0 Gallons Per Hour or up to 450 PSI depending on model selection. Higher capacity solenoid metering pumps, such as the LMI C Series can achieve up to 25 Gallons per Hour at 300 PSI. There are two main components of a solenoid driven metering pump: the drive and the liquid end.

Justification of the choice of pump drive for pumping ...

One of the key conditions for the dynamic development of oil trunk transportation is to reduce the cost of pumping whose important component is energy costs. Energy transportation costs can be reduced by choosing an optimal type of the drive for pumping stations during construction and reconstruction of existing oil pipelines. An alternative to the electric drive can be a gas turbine.
