Informed selection of sanitary pumps is important and making proper use is also vital to ensure the food processing operations success. The technological breakthrough is apparent in the materials and pump design of construction resulting in new pumping applications and equipment explosion. Misunderstanding and confusion of sanitary pumps go hand-in-hand with new equipments, so having a clear classification with respect to pumps ensures good pump selection.
Right from sanitary liquid products handling to food and beverage applications or a pharmaceutical or dairy processing, there is a need to have highly engineered dedicated manufacturing of sanitary centrifugal pumps so that seamless operation and smooth processing is ensured.
Taking into consideration about downtime is mandatory as it also involves money. Thus, there is a need to produce innovative quality centrifugal pumps that meet the needs of sanitary applications and also ensure there is an inventory that is well-stocked.
Centrifugal pumps at process plants are ubiquitous, but many do not understand the way of selecting and also installing. There are rules to be applied and going through each detail is the catch. Pump selection should begin with system curve such that the plants supplying the vendors must address the system curve to 80% process of pump selection. Regrettably, the plant-supplied system curves lead to excessive costs.
Developing the curve is about establishing the layout of the piping and this allows flow rates and system pressures to be considered or taken into account. The isometrics are drawn and the system curve graph is calculated. The flow or pressure rate plot represents the process changes. This is essential to know and must be considered and the pump vendors should offer valid recommendation.
Determining the suction side static, friction heads and velocity is important. So comparing these plats is essential. The intersection of the pump and system curve alone represents the design point. At the same time, selecting particular sanitary pumps should be done with care. Choose the one featuring greatest distance between minimum and maximum size as revealed on the pump curve.
Comparing pump curves involves engineering experience and judgment. Only then the pumps will operate at equal flow rates in comparison to the system curve. Ensure the wheel is larger so that the efficiency of the pump allows operating at best efficiency point. Ignoring the efficiency of the pump, shaft length, BEP operation, and horsepower required, diameter, adaptability process and NPSHR is impossible as these dominate typically the design criteria.
