TIGERFLOW CD10 Vertical Multistage Pump End - Wet End Only, 44 GPM Nominal

This is the CD10 hydraulic end on its own: base, stainless impeller stack, cartridge seal and motor stool, ready for a NEMA TC-frame motor. Use it to rebuild a CD10 without replacing a sound motor, or to pair the pump with a motor you already hold. The model number gives the nominal flow (10 m3/h, about 44 GPM) and the stage count; the motor frame each model takes is in the option list and in the table below. Fill and vent the pump before it starts.

• Hydraulically balanced; impellers and guide vanes stamped and laser-welded on robotic equipment
• Cartridge-style mechanical seal for fast removal
• Designed for use with different standard motors
• 304/316 stainless impellers; cast iron or 316 head and base by construction

Motor each pump end takes (ordered separately)

Frame from the TIGERFLOW 2026 price list; horsepower from the complete-pump builds in the same price list and the CD Series catalog.

With the motor fitted, each pump end develops the pressure below, in PSI. The first column is the shut-off, the most the model can make.

CD10 · Pressure in PSI at the flow shown · smaller models · curves end at 74.8 GPM

CD10 · Pressure in PSI at the flow shown · larger models · curves end at 74.8 GPM

Read from the published CD10 curves in the TIGERFLOW CD Series Vertical Multistage Pumps catalog (60 Hz, 3500 RPM), pp. 17-18, digitized from the catalog’s vector curve data and rounded down to whole PSI. Zero flow is the shut-off point — a ceiling, not a working point; TIGERFLOW prints no separate shut-off figure, so the 0 GPM column is where the dashed part of each curve meets zero flow. The solid (recommended) part of each curve starts at 26.4 GPM; 28 GPM is the first column inside it, the next two sit near 50% and 75% of the curve end, and the last column is the last regular digitized flow every curve reaches (the curve end is named above the table where it runs a little further). Single- and three-phase builds and the HP options of the same model run on the same curve. Feet of head = PSI × 2.31. The full curve, with power per stage and NPSHr, is in the image gallery.

Best operating range: 26.4 to 74.8 GPM, the solid section of the published curve.

• Make sure the motor you connect meets all the pump’s technical requirements (frame, HP, 2-pole speed).
• Bolt the base to a flat, solid stand that carries the whole base plate; support every pipe independently of the pump.
• Check rotation at start-up: counterclockwise seen from the motor.
• Fill and vent before start, then open the discharge valve slowly.
