Spacing saving vertical pump system design reduces footprint in university’s mechanical room.
A major North American university needed a new science building to address the space requirements based on evolving educational needs. The new laboratory building was constructed to LEED (Leadership in Energy and Environmental Design) standards. An advanced mechanical room was required to ensure the building would operate sustainably and efficiently. The engineering firm faced the challenge of designing a multi-million-dollar system that would adjust to new requirements in terms of flexibility, while maintaining a small footprint. The system, consisting of six layers of piping and 16 pumps, required a specific sequence of installation, and had to meet specific seismic mounting and vibration requirements.
i-Alert Equipment Health Monitors - condition sensors, pressure sensors along with the new i-ALERT Gateway offer class-leading continuous machine monitoring of vibration and temperature with comprehensive wireless reporting. With this system, you can:
CBD Oil extraction requires low temperature ethanol pumps.
Viking Pump offers 2 pumps that will meet the pressure and temperature requirements of cold ethanol extraction. Hayes Pump offers local support & service as an authorized Viking Pump service center.
Mission Communications hosts free, informational webinars every Wednesday. Everyone interested in learning more about the fully pre-packaged, cost-effective, turnkey SCADA is encouraged to join.
These interactive webinars are designed for users to ask live questions about any monitoring or Mission subject they would like addressed. The focus of the webinars will vary week-to-week, with the general subject matter repeating on a month-to-month basis. Customers are welcome to ask questions about monitoring and Mission-related topics even if they are not covered by the topic of the week. When signing up for the webinar, GotoMeeting software will be automatically loaded to the desktop, laptop, or mobile device. Users can use the microphone and speakers of their device to listen to the audio and ask questions or dial into the toll-free number that is provided at the start of the event.
Water Waste Reduction Solution
A chemical processing plant wanted to reduce the amount of water it used to process lithium hydroxide used in batteries. The water waste was linked to packing used on a pump in the hydroxide and limestone slurry process, leaking onto the concrete floor and red clay soil. Excessive water consumption, constant packing service, EPA concerns and facility structural heaving damage were among the reported issues.
Motor design is key to the performance and service life of a pump. But determining the size of the motor required to drive the pump is something people often struggle with. This is especially true of wastewater submersible pumps.

It’s a common assumption that you can use motor nameplate information at face value. That applies to some, but not all nameplate data. A primary example is service factor (SF).
Generally, service factor is the measurement used to determine the peak performance at which a pump motor can operate. The National Electrical Manufacturers Association (NEMA) defines service factor simply as a multiplier that indicates the amount of additional load a motor can handle above its nameplate horsepower. The service factor industry standard for a totally enclosed motor is 1.0.
To determine the service factor horsepower of a motor, multiply the nameplate horsepower by the service factor. For example, if a 1 HP motor has a service factor of 1.5, the motor’s service factor maximum horsepower is:
(1 HP) x (1.5 SF) = 1.5 HP
However, when sizing submersible wastewater pump motors, horsepower service factor, which applies only to the motor, is not a primary consideration. While service factor can be used to handle intermittent or occasional overloads, designers cannot rely on the service factor capability to carry the load on a continuous basis. Doing so will likely result in reduced motor speed, and the reduced life and efficiency of the pump.
Designing Pump Systems for Continuous Duty
When sizing a submersible wastewater pump motor, it’s important to consider whether the pump will ever be required to operate at a flow rate higher than the design point. If, for example, the pump was allowed to operate at the end of the head capacity curve, the actual horsepower requirement may exceed the design point selected motor horsepower and overload the motor. For this reason, it is common practice to size the motor not for the design point, but for the end of the curve or maximum horsepower requirements.
In the example above, a 7.5 HP motor would adequately power the pump at a design point of 120 GPM at 150 feet; however, looking at the end of the curve, brake horsepower requirements call for a 10 HP motor.
It’s also important to note that submersible wastewater pumps follow Affinity Laws – the mathematic relationships that allow for the estimation of changes in pump performance as a result of a change in one of the basic pump parameters. If either the speed or impeller diameter of a pump changes, you can approximate the resulting performance change using the following:
Pursuing peak pump performance
Taking all of these factors into account, the NOL Horsepower (or non-overloading brake horsepower) is a more accurate criterion when it comes to sizing the motor for a submersible pump. The NOL Horsepower is the maximum power value calculated in order to handle the maximum power demanded by the pump at any point along the curve. NOL Horsepower represents the amount of real horsepower going to the pump, not just the horsepower used by the motor.
Although not typically listed as part of the operational information on the pump nameplate, NOL Horsepower is one of the key factors confirmed during pump performance testing. If motors overload at any point on the published curves during testing, listing agencies like UL and CSA will not award product certification to the motor vendor.
While the factors used to size a motor that will operate anywhere on the pump curve may not be those typically used as defined for standard NEMA motors, there are advantages. Selecting a pump/motor combination that will function under all possible operating conditions will result in higher efficiency, longer service life and uninterrupted performance — even in a continuous duty application.
The NEW Chemineer JT-2 Impeller has been designed for a difficult application - blending high viscosity and non-Newtonian fluids. The JT-2, a transitional flow impeller, is specially engineered for situations where conventional turbines have lost their efficiency due to viscous effects, but you don't yet need a close clearance impeller. The JT-2 provides up to 50% reduction in power draw for the same blending performance compared with competitive impellers.
