High Pressure Misting Pump Selection

Size flow for the active zones

Build a nozzle schedule for each zone. Add the flow of every nozzle that can run at the same time, using its confirmed flow at the intended nozzle pressure. A mixed-nozzle line needs a separate quantity and flow for each model.

• List simultaneous and alternating zone combinations
• State any flushing or bypass demand separately
• Include line length, elevation and component pressure losses

Match the duty point, not two maximum values

Specify the required flow and discharge pressure together. Check the pump performance data at the proposed speed and the pressure needed at the most disadvantaged nozzle. Maximum flow, maximum pressure and motor power are not independent promises of performance.

Choose a single pump or modular station

A single pump package and a multi-pump station have different part-load and maintenance requirements. Compare the smallest and largest active loads, permitted zone overlap and the consequence of taking a pump out of service.

• Identify duty pumps and any specified standby pump
• Define the allowed speed range and pressure-control method
• Confirm inlet supply, bypass routing and service access for each pump

Confirm the electrical and mechanical package

Request the exact pump and motor models, duty data, voltage, phase, frequency and drive arrangement. Confirm the inlet conditions, seal and wetted-material compatibility, protection devices and connection sizes for the selected package. Black hydraulic hose assemblies with crimped fittings connect the illustrated pump package. Specify hose bore, end connections and routing; confirm the selected assembly is suitable for the system water, pressure and temperature.

• Pump model, speed, flow and pressure at the selected duty
• Motor power, supply and continuous or intermittent duty
• Regulation, secondary pressure relief and low-water protection
• Included filters, valves, controls, spares and installation responsibilities

Prepare a comparable pump quotation

Send the zone schedule, nozzle operating data, line layout, water supply, electrical supply and daily operating hours. Ask for a configuration-specific datasheet and a clear list of included and excluded items; do not compare pump sets on motor power alone.
