คู่มือเลือกปั๊มสุขอนามัยสำหรับโรงงานเครื่องดื่ม

List viscosity, density, temperature, particles, gas content and shear sensitivity for every duty. One pump family may not suit both product and CIP return.

Calculate static head, pipe loss, valves, equipment pressure drop and operating range. A nominal flow without the system curve cannot define the duty point.

Review tank level, elevation, vapor pressure, pipe geometry and start sequence to protect NPSH margin and prevent cavitation.

Specify seal arrangement, flush or cooling needs, dry-run exposure, product compatibility and replacement access.

Define VFD range, minimum stable flow, permissives, valve coordination and response during line stops or tank changeover.

Confirm cleaning velocity through the connected circuit, casing drainage, orientation and whether the pump must handle both supply and return conditions.
