Stainless Steel Pump Production

Since the early ’80s, when stainless steel pumps were introduced to the pump market, stainless steel products have faced slow acceptance to date. Comparing the structure of the manufacturing process to that of the traditional cast iron or bronze pumps and parts, the quality, construction, and durability of stainless steel manufacturing faced controversy.

The Secret Is Out: The Advancement of Submersible Pumps

Most of us have viewed with fascination the rapid development and evolution of computer technology in recent years, while perhaps overlooking some important technological advancements in the less glamorous, but nonetheless vital, process machinery sectors. Solid advances in basic machinery such as submersible pumps have demonstrated a measurable potential to enhance basic process tasks, increase equipment dependability and provide a long-term reduction in everyday operating costs.

Selection Criteria for Wastewater Pumps, Part 3

Submersible Pumps in the Dry Well

A "standard" submersible pump cannot operate in a dry well because it must be submerged in order to cool the motor.

The construction costs associated with this alternative are shown in Table 6 and compared with the construction costs for the conventional wet well/dry well design previously described.

Application Possibilities Grow for Plastic Pumps

No matter what design solutions engineers and construction contractors devise to contend with the growing number of water and air pollution regulations, they can't do very much without pumps. Gravity sometimes may play a role in water and wastewater systems, but pumps are without a doubt the prime movers in the business of fluid handling.
