The primary causes of pump failure are process-related issues that can shorten a pump's lifespan, such as dry running, low flow, closing valves improperly, or cavitation. While pumps are designed to operate reliably for years, operating conditions can damage pumps. Monitoring pump power can detect problems early and prevent damage. A power monitor pays for itself by reducing maintenance costs from preventing failures. It monitors power draw and shuts off pumps if power levels exceed set limits, detecting issues like dry running or bearing failure.

1. The primary cause of pump failure is process
related, which is true for both sealed and
sealless pumps. Most process-related failures
are triggered by:
• Dry running or low flow
• Closing valve on suction or discharge
• Cavitations or vapor in pump
• High flow overload
In theory, a well-designed pumping system
should quietly and efficiently continue to
work for years. Unfortunately, the reality is
that any number of operating conditions,
such as those noted above, can dramati-
cally shorten the life of the system.
To save upfront costs, many pump systems are
installed without an option to continually monitor
operation. This results in frequent inspections and
visits, which are necessary to maintain and repair
the monitor-less systems. If a failure occurs without
warning, irreparable damage to either the pump
or the motor can result. A power monitor system
adds very little cost upfront at time of installation
and basically pays for itself when a pump is first
installed.
It’s shortsighted not to eliminate all the resulting
problems a power monitor can detect. The device
monitors the actual power absorbed and immedi-
ately shuts off the pump if it falls below a predeter-
mined value or goes above its upper set limit.
Monitoring pump horsepower provides the ability
to determine exactly what’s taking place with the
fluid. In an existing pumping system, there will
be power changes that the monitor will detect,
especially when the discharge valve is opened
and closed frequently. Dry running, no priming,
clogged inlet, or cavitations can be determined
with low-power detection, while jammed impeller
by rear, forward thrusting, and bearing failure can
be determined with high-power detection.

Protecting Your Pump with Power Monitoring
It’s penny wise and pound foolish not to
specify a power monitor with your pumping
system. It is an efficient, cost-saving accessory
for any of your pumping applications.
Ready, set, go to the Stock Depot or Sundyne
to determine the power monitor that is right for
your specific pumping system.

KontroQuarterlySalute The Kontro Quarterly Salutes Sam Cheetham
Over the years, it’s been a pleasure working with and getting to know
Sam Cheetham. Sam began an apprenticeship at HMD Kontro that
turned into full-time employment. During his two-year apprenticeship from
ages 14 to 16, Sam worked in the following departments: Machine Shop,
Tool Room, Mag Cell, Shroud Test, Fitting Shop, Paint, Internal Sales, Engineer-
ing, Customer Service, and Contacts.
When his apprenticeship was finished, Sam opted to spend the next two years
in the company’s machine shop, working on manual and CNC machines that
manufacture pump components, in addition to producing fixtures and tools for
the machines.
Now with eight years as a full-time employee, Sam has been with the company
his entire working life. He wouldn’t have it any other way. Sam considers all the
people at HMD Kontro his family. They are the favorite part of his job.
Sam’s extensive experience within so many areas of the company has formed the backdrop of his current role
as an HMD Kontro engineer. He gets to meet people from every part of the world and every walk of life. Sam’s
position has provided him the opportunity to travel to the USA, Latin America, Europe, the Middle East, and
the Far East.
Sometimes hectic but never boring, Sam’s
job keeps him on his toes. Supported
by a great team of people with extensive
knowledge of pumps and systems, Sam
proudly declares, “They’re always willing to
take time to teach me new things that help
me grow as a engineer.”
Sam is big on sports, whether playing or
watching. He plays football (aka soccer)
with his friends, as well as tennis and bad-
minton. He’s recently returned from a trip
to France, where he had tickets to watch
five matches at this year’s International
European Championship. He also loves
watching rugby, regularly traveling to
London to watch the Harlequins play –
or sometimes England when he’s lucky
enough to get tickets! In the picture above,
Sam and his nephew are both wearing
their England Rugby jerseys!
Sam loves music and spending time with his family at home. He and his girlfriend Courtney recently bought
their first house together, so a lot of Sam’s spare time this year has been dedicated to home improvements.
The Kontro Quarterly proudly salutes Sam Cheetham, a true asset to the HMD Kontro family, a talented engineer,
and a good man.

Success Story
One of Corrosion Fluid Products’ best customers was in urgent need of an HMD Kontro model GSA / ANSI
dimensional (1 x 1.5 - 8) pump. A strong believer in HMD Kontro pumps based on a history of use, the
customer required that the new pump have a special option: it had to be fitted with Kalrez o-rings due to
the type of process fluid it would pump.
Customizing the HMD Kontro pump required an 11-week factory lead time. What to do? The Stock Depot
came to the rescue with both the pump and the Kalrez o-rings in stock. Quickly going to work, the Stock
Depot refitted the stock unit with the special o-rings and shipped the customized pump in two days. The
turnaround was nothing short of miraculous. The customer was delighted to have the special HMD Kontro
pump so quickly and remains a loyal CFPC and HMD Kontro customer.
This success story is an example of the Stock Depot’s extensive inventory and outstanding service that
enables it to efficiently serve distributors with their HMD Kontro pump needs.
