Having a proper insulation system for an electric motor is important for protecting the motors from shorts and contaminants.
How the difference between mechanical and chemical pulp affects the calculation.
Understanding wastewater disinfection to ensure safe effluent release
The primary benefit of condition-based monitoring is that high cost or unexpected failures can be mitigated, and the maintenance can be scheduled during a convenient time for plant operations.
PARSIPPANY, N.J. – The Hydraulic Institute (HI) and the Consortium for Energy Efficiency (CEE) have announced the signing of a Memorandum of Understanding (MOU) to formalize their collaboration in advancing energy efficiency in commercial and industrial pumping systems. The MOU was officially executed on July 9, 2025, marking a significant step toward accelerating market adoption of high-efficiency pump technologies.
Pressure is an important factor influencing the closing force between the seal faces, and the seal design may need to be adjusted to accommodate higher pressures.
Using the Darcy-Weisbach friction factor to calculate this major loss.
An in-depth look at the Hydraulic Institute’s new certification training program.
Proportional pressure is a control method that varies the speed of the pump according to a pressure algorithm.
The steps to find a single minor loss, specifically the bell-mouth inlet, the square-edged inlet and the inward-projecting pipe.
In this motor type, there is no induced current in the rotor, which eliminates the induction losses and results in increased efficiency, higher power density and lower heat generation.
What are the requirements for pump to motor shaft coupling alignment?
