A Step-by-Step Approach to Pump Selection | Pumps & Systems

Unless a brand new plant is being designed, users decide to replace a pump because of its age and wear or persistent reliability issues. Plant engineers typically spend their time with the process to make sure machinery is working, water is flowing, power is produced, lights are up and no environmental problems are developing. They are not, as a rule, experts on any particular type of machinery.

Nozzle Guide and Charts - Norton Sandblasting Equipment

Nozzle material selection depends on the abrasive you choose, how often you blast, the size of the job and the rigors of the job site. Here are general application guidelines for various materials. Aluminum oxide "alumina" (ceramic) nozzles offer good service life at a lower price than other materials discussed here. They are a good choice in low usage applications where unit price is a ...

Sieve analysis - Wikipedia

With careful selection of the gradation, it is possible to achieve high bulk density, high physical stability, and low permeability. This is important because in pavement design, a workable, stable mix with resistance to water is important. With an open gradation, the bulk density is relatively low, due to the lack of fine particles, the physical stability is moderate, and the permeability is ...

Tightening & Torque Recommendations for Hydraulic Couplings

The art of making a leak-proof connection with hydraulic couplings is to tighten the couplings properly at the time of installation. An overtightened coupling may be just as apt to leak as an under tightened coupling. This is because over-tightening a coupling may result in overstressing and/or cracking. The torque values in the following table give minimum and maximum torque recommendations ...

Practical Considerations in Pump Suction Arrangements

An important aspect of pump hydraulic system design is the suction or inlet conditions. Disregard for proper allowances can result in vortices, cavitation, and loss of prime. Pumps do not force liquids through inlet or suction piping, but rather create lowered pressures at the suction nozzle which in turn in-duces the fluid to enter. Any design that impedes or lessens the .
