Motor insulation deteriorates faster at higher temperatures
HI Pump FAQs
These are manually set and do not react to pump and system changes.
In some cases, sudden valve closures can cause high pressure spikes.
These bearings are located within a containment shell with no shaft exposed to atmosphere
A liquid-lubricated seal may have no visible leakage.
There has been an effort to upgrade pumps originally designed for packing to accommodate mechanical seals.
Can coatings be applied to increase the efficiency of a pump?
Forced vibration is due to a mechanical or hydraulic component of the pump
VSDs allow the pump speed to be lowered or increased
Understand types of PD pumps for this application
What material considerations should be made?
Acceleration transducers (accelerometers) are typically used to measure vibration on stationary components.
The design does not use a dynamic shaft seal as a primary containment device.
Accumulations of solids must be cleaned for safety reasons, among others
Shaft sleeves and bearings are among replacement parts needed
Correction factors determine head and efficiency curves for the pump when handling viscous liquids.

The proper grease should be chosen based on factors such as moisture, bearing load, speed, temperature and shaft orientation.
The conductivity probe and float switch are the top sensors used.
