Maintenance Minders

Cavitation is a destructive condition that can destroy the inside of a pump before you even realize it is occurring. Early detection can minimize damage, reduce downtime, and save money. Cavitation involves the creation of bubbles formed when the fluid being pumped vaporizes due to a decrease in pressure as the fluid enters the pump. These bubbles are then acted on by the pump impeller, causing them to implode.
Data and life cycle management technology helps refineries maintain equipment and reduce the total cost of ownership.
Vertically mounted pumps can resonate as a total structure in a "rocking" mode, as shown in Figures 1 and 2 below. This is one of the toughest unsolved vibration problems at several plants.
Thorough preparation and the right alignment method are critical.
Options to develop PM plans vary from very simple one-time development to living programs. Picking the choice that best meets your needs comes down to your business case. pump maintenance
With today’s energy prices and the need to reduce emissions, a plant cannot allow its steam/condensate systems to vent flash steam to the atmosphere.
A simple maintenance routine can help ensure trouble-free valve operation.
Identifying the source of vibration by following the amplitude: the case of a company that thought the problem was a pump impeller, but, in fact, the problem was over 15-ft away and not a pump at all.
Follow some little known rules to keep your pumps working at their best for longer.
Editor's Note: This is part two of a two part series about the 'commandments' of increasing pump reliability and life.
Your pumps benefit from regular checkups to ensure no underlying problems exist.
Do you need help with a pump problem and want to know how other pump users would solve it?
Power plant slashes maintenance time and labor costs dramatically by switching to split design mechanical shaft seal.
Today's lean maintenance staff needs pump and motor protective devices that diagnose and predict problems before they become acute.
In today's growing industrialized market, the need for reciprocating pumps is increasing daily. As technology drives modernization, the demand placed on the pumping systems is continually rising.
Construction features are key to vertical motor application and maintenance.
Initial purchase price is a small fraction of the TCO.
As peristaltic pumps are true positive displacement pumps, they will deliver a consistent flow rate as the discharge pressures vary.
Pressure gauges are an important indicator of whether a system or component is operating correctly. Pressure gauges generally require little to no maintenance, other than periodic calibration. However, if gauges require minimal maintenance, why do some seem to continually wear out?
Establishing an effective pump reliability program can slash costs, make operations safer and provide uptime benefits.
For more than 25 years Shock Pulse has proven to be a valuable method for evaluating bearing condition.
Lubricated machines require clean, dry oil to work properly.
