Eta Pump

Eta Pump. Description Product features Usages The characteristic curves Horizontal longcoupled singlestage volute casing pump in back pullout design ratings and main dimensions to DIN 24255 Replaceable shaft sleeves / shaft protecting sleeves and Impeller wear rings.

The upper efficiency curve (Eta2) is the pump efficiency curve (eta pump) The lower efficiency curve (Eta1) is the total efficiency curve (eta pump + motor) taking all electrical mechanical and hydraulic losses into consideration.

“What is [Pump+Motor] Eta” fluid horsepower / electrical input power “Is this an efficiency term” my understanding of your most recent post is you agree in this context eta means efficiency “what is the difference between motor efficiency and pump Eta” motor efficiency = shaft horsepower / electrical horsepower.

The first pump is the ideal choice based on your sizing criteria and life cycle cost Step 3 Choose your desired product Choose a specific pump to review indepth pump information Select the print option if you would like to make a PDF of the pump and print the relevant data you need such as sizing results curve duty points installation and pump dimensions Go to pump sizing.

How to do pump sizing by application Grundfos

A centrifugal pump imparts energy on a liquid and based on the system has flow and head characteristics The amount of required pressure the pump must overcome dictates where the performance point will be on the curve and how much flow is produced As pressure increases the flow decreases moving your performance point to the left of the curve.
