Many types of pumps are suitable for use in the food industry, including rotary lobe, rotary piston, reciprocating positive displacement and air-operated double diaphragm designs. Traditional pumps, however, can be expensive to maintain while lobular pumps have low flow rates.
Xylem expanded its pump portfolio to include e-MP multistage ring section pumps, e-XC single-stage, double-suction centrifugal pumps and larger vertical turbine pumps. The pumps are designed to address issues in industrial pumping and processes, including minimizing downtime and environmental impact, and boosting and transporting water as efficiently as possible.
Evaporative cooling has been around for centuries. Also called adiabatic cooling (particularly in Europe), evaporative cooling is the earliest form of air-side cooling known to man. In spite of that, it also is probably the least understood — and sometimes maligned — solution to cooling.
Maker of nonmetallic sealless pumps has added a 316 stainless steel metallic sealless pump line. The Iwaki Sanwa line will include two series of pumps. Series MP offers flows to 340 gal/min while the smaller Series MMP will be a fractional-horsepower offering with flows to 24 gal/min.
When sizing, selecting and installing hermetic pumps in refrigeration units, there are many considerations. This article will explore the types of pump as well as provide a guide for troubleshooting common problems.
Series MM have food-grade wetted materials and a construction that enables clean-in-place (CIP) and sanitize-in-place (SIP) capabilities. The pump design incorporates soft redirections without rotating parts and shaft seals in the product chamber.
When compared to space cooling, process cooling — or the removal of heat from the fluid that serves water-cooled equipment used in a manufacturing process — is a bird of a different feather. Interesting though — and the source of some fascination among those in the cooling trade — is that much of the equipment, tools and techniques remain the same.
A portable, clean-in-place pump system, Model GDS-100 is suited for larger descaling cleanings to remove limescale, calcium and mineral deposits, rust and other contaminants found on process manufacturing equipment.
