The TIGERFLOW CD1 is a vertical multistage centrifugal pump: suction and discharge in line on a common base, stacked stainless steel impellers, and a NEMA TC-frame TEFC motor on top. TIGERFLOW builds it for pressure boosting of potable water, solid-free water in industrial and municipal plants, fire-system jockey pumps, boiler feed, HVAC circulation and irrigation. The model number gives the nominal flow (1 m3/h, about 4.4 GPM) and the stage count: more stages, more head at the same flow. Fill and vent the pump before it starts; it does not prime itself.
Included: the CD1 pump end and its TEFC motor, coupled as one complete pump, with 1-1/4 in ANSI Class 300 flanged suction and discharge.
Motor protection required, ordered separately. TIGERFLOW calls for a motor-protective circuit breaker set to the motor’s current, with the connection made by qualified personnel to the regulations in force. A drive or starter with overload protection does the same job.
Companion flanges, isolation valves and a non-return valve: sized to your piping and ordered separately. TIGERFLOW calls for isolation valves on both sides of the pump and a non-return valve against backflow; our NPT companion flange kits fit the 1-1/4 in Class 300 ports.
Covered by TIGERFLOW’s one-year guarantee under normal operating conditions, as stated in the CD Series installation, operation and maintenance manual. Wearable parts are not covered by the guarantee, and any inadequate use of the product voids it (manufacturer’s wording).
Each CD1 runs as one complete pump. Size it to the full peak demand at the pressure you need.
| Nominal flow | 1 m3/h (about 4.4 GPM) |
| Horsepower | 1/2-2 HP; motor frames 56C, 182TC |
| Motor | NEMA TC frame, TEFC, 2-pole, 3500 RPM, 60 Hz; 115/230V 1Ph; 230/460V 3Ph |
| Connections | 1-1/4 in ANSI Class 300 flanges, in line |
| Maximum working pressure | 362 PSI (25 bar) |
| Liquid temperature | 5°F to 248°F (product guide); the manual lists the standard type to 158°F and the hot water type to 248°F |
| Ambient and altitude | 104°F maximum ambient; 3,280 ft maximum altitude |
| Mechanical seal | Cartridge seal, carbon / silicon carbide / Viton (standard) |
| Certification | NSF/ANSI 61 and NSF/ANSI 372; cULus Listed |
| App or remote connectivity | None — it runs from the starter, breaker or drive it is wired to |
TIGERFLOW’s CD Series catalog and product guide print curves for CD3 to CD85; the CD1 is in the 2026 price list without a published curve on file. Email sales@watermainsupply.com for the CD1 curve and a factory submittal before you order; we size it against your duty point.
| Maximum pressure | Incoming pressure plus the pump’s shut-off pressure must stay below 362 PSI, TIGERFLOW’s maximum operating pressure. |
| Suction | Fill and vent before start. A suction lift is possible only where H = barometric pressure × 2.31 − NPSHr − friction − vapor pressure stays positive; where H is negative, that much inlet pressure must be guaranteed (manual). |
| Minimum flow | Run it with water flowing: never against a closed discharge valve, and never below the minimum recommended flow, or the pump overheats. Dry running damages the bearings and shaft. |
| Power | 115/230V 1Ph; 230/460V 3Ph by build; the supply must match the nameplate, with a motor-protective circuit breaker. |
| Water | Clean, solid-free water. Certified to NSF/ANSI 61 and NSF/ANSI 372. |
| Temperature | Liquid 5°F to 248°F (guide; 158°F on the standard type per the manual); above 104°F ambient the motor must not run at full load. |
