What is Pump Cavitation and Its Common Causes?

August 13, 2018

There's a drive-hampering phenomenon that we've mentioned several times in past articles. Referred to by engineers as "Pump Cavitation," the issue attenuates flow performance. Again, that fact has been covered several times, but what is cavitation? Pump repairers must understand this fluid effect, must know all about its causes and the conditions that produce the flow-hampering issue. For starters, is cavitation really just a verbose way of talking about bubbles?

The Role of Coupling Rods for Progressive Cavity Pumps

July 25, 2018

There's a prime mover on the floor, bolted to a concrete plinth. Further down the line, a progressive cavity pump is ready for its first day of work. Moving between those two key drive sections, there's the coupling rod. This is the bridging or connecting component that hooks the prime mover to the pump mechanism. Starting at the drive shaft, let's see where the powertrain takes the rotating energy.

Signs of Problematic Drive Shafts in Pumps

April 26, 2018

A drive shaft, or drive shaft, is one of the most important central mechanical components within your pump. The drive shaft is used as a bridge for kinetic energy to be transferred in order for the entire pump to properly operate. As such, your drive shaft will have to be able to endure constant rigours and stress despite being in the relative comfort of the pump's housing. In order to keep your impeller rotating, you need a healthy drive shaft.

Accuracy of Universal Rotor Cutting Machines for Pumps

February 28, 2018

A look at a universal rotor cutting machine takes us neatly into familiar territory. As mentioned previously, the machined helical geometry assigned to this rotating shaft isn't cut arbitrarily. Quite the opposite, the rotor cannot form a fluid-conveying relationship with its stator unless it's machined accurately. This interference fit facilitates the formation of discrete fluid packets. Cut poorly, those isolated fluid packets will leak. Let's talk about rotor-cutting accuracy.
