Xylem Inc.’s Bell & Gossett brand has a new parallel sensorless controller, a device that provides advanced system staging of up to eight pumps in parallel configuration to maximize system efficiency. The large 5.7-inch touch screen displays real-time feedback and enables energy modeling.
Jet pumps are used for a variety of applications involving the movement of water from a water source to a destination. If your home is supplied primarily by well water, you may need a jet pump to pull the water.
Pressure gauges and switches are among the most often used instruments in a plant. Monitoring your gauges and regular maintenance can help you avoid expensive and unexpected shutdowns.
The key component in most rotating equipment is the shaft. A shaft is the mechanical component for transmitting torque and rotation. Shaft size greatly affects the torque in these machines. Hence, the precise design and prototyping of shafts is crucial for all applications.
Choosing the proper material can maximize reliability. When considering the best material for your electric motor shaft, there are several considerations: Cost and Material Deficiencies.
The material used for ordinary shafts is mild steel, but when high strength is required, an alloy steel such as nickel, nickel-chromium or chromium-vanadium steel is used.
Most motor manufacturers use SAE 1045 in either cold-rolled (CRS) or hot-rolled steel (HRS). C1045 is a medium carbon, medium tensile steel supplied as forged or normalized. This steel shows good strength, toughness and wear resistance.
Armstrong Fluid Technology has announced the availability of a new line of high performance Design Envelope End-Suction pumps in the 1 to 10 hp range.

When you’re at home and the power goes out you can light candles, but if you have a power failure at your business you need a better solution. You may want to invest in an emergency-power backup.

Commercial building managers are challenged to improve the energy and water efficiency of their buildings. This is driven by new building codes that continue to raise efficiency standards for new and existing buildings, pressure to cut energy costs wherever possible and corporate sustainability initiatives. Facility managers of existing properties are increasingly adopting a systems approach to energy and water efficiency improvements.
Variable frequency drives are also called frequency inverters and AC drives. These are electric devices used to change the utility power source to variable frequency to control an AC motor in variable speed operation.
This adjusts the speed of an HVAC fan, pump motor or commercial electric motor based on demand. This will help lower your energy costs while also extending the life of the commercial & industrial motor and the mechanical components.
A HVAC fan or pump motor is either on or off. There is no in between. Add a VFD and you will eliminate the initial power surge and mechanical shock when the motor is switched on.
There are many reasons for low water pressure: buildings above the water supply lines, gravity, and commercial buildings that are tall and require additional water pressure to serve upper floors. (On current new construction and retrofit projects, water pressure booster pumps are used to provide adequate water pressure to upper floors of high rise projects.)

Shafts are a key component in most rotating equipment. When they are not working properly, it can cause huge problems and cost lots of money, not only in down times but increased energy bills.
