CR 64-5-2 H-G70-A-E-HQQE

Overview

5-stage end-suction horizontal pump configured as CR 64-5-2 H-G70-A-E-HQQE. Rated flow 337 US gpm at a rated head of 467.5 ft and a maximum head of 584.3 ft at a rated pump speed of 3550 rpm (60 Hz). Maximum operating pressure 435.11 psi; pressure rating PN 40; flange rating inlet 300 lb; pressure rating for connection PN 40; curve tolerance ISO9906:2012 3B. Pumped liquid: Water; selected liquid temperature 68 °F; liquid temperature range -22 .. 248 °F; density 62.29 lb/ft³. Mechanical materials: base/casing Cast iron EN 1563 EN-GJS-500-7 / ASTM A536 80-55-06; impellers Stainless steel EN 1.4301 AISI 304 with 5 impellers total and 2 reduced-diameter impellers. Sealing and bearings: primary shaft seal HQQE with single shaft seal arrangement; bearings listed as SIC with Graflon support bearing. Connections and interfaces: suction port 4 inch, outlet port 3 inch, type key/code for pipework connection G70, flange size for motor 324TC, motor standard NEMA. Shipping and handling: net weight 262 lb, gross weight 423 lb, shipping volume 28.9 ft³. Approvals and origin: CE, NSF/ANSI 61 on nameplate; country of origin US; product no. 97681739. Designed for industrial high-head water transfer and pressure applications where 337 US gpm at several hundred feet of head is required; duty points up to 584.3 ft head and service pressures up to ~435 psi. The horizontal end-suction, multistage layout and 4" suction / 3" discharge connections suit installation on packaged pumping skids or within pump rooms with standard ANSI/PN40 piping flanges. Material selection (cast iron casing, AISI 304 impellers), NSF/ANSI 61 approval and the specified liquid temperature range (-22 .. 248 °F) make it appropriate for municipal and industrial potable water, pressure boosting, and other water-handling systems operating at ambient to elevated temperatures. The unit is supplied without a frequency converter; motor mounting (324TC) and NEMA motor standard allow integration with customer-supplied drives and controls. Maintenance and reliability considerations: single HQQE shaft seal and SIC/Graflon bearing arrangement define spare-parts and service requirements for seal and bearing replacements.
