A.02 MR - 6XC turbine curve - 5 hp.pdf

This is a Pump Performance Datasheet for a centrifugal pump quoted by Wilo for Cascade Machinery. The document specifies a single 7-stage, 6XC size pump (Item 001, Quote 2794884) with a rated flow of 120 USgpm and differential head of 99.03 ft at a supply frequency of 60 Hz. The pump operates synchronously at 1,775 rpm with a 4.38-inch rated impeller diameter and delivers an efficiency of 72.98 percent. The pumped liquid is water at a maximum temperature of 68.00°F with a density of 1.000 SG and viscosity of 1.00 cP.

The pump is constructed of cast iron and requires a minimum recommended motor rating of 5.00 hp or 3.73 kW, with a hydraulic power requirement of 3.00 hp and actual power consumption of 4.11 to 4.20 hp depending on bowl configuration. Performance curves included in the datasheet illustrate the pump's head-capacity relationship, efficiency profile peaking near 120 USgpm, and NPSHR (Net Positive Suction Head Required) characteristics across the operating range. The document indicates acceptable selection status with a 0.50 ft margin over the required NPSHR and references additional pressure data available on a supplementary page.
