Taco Vertical Split-Coupled In-Line Pumps (KS / SKS Series)

Taco KS pumps combine a space-saving vertical in-line arrangement with hydraulically balanced impellers for efficient operation, reduced bearing loading and low NPSH requirements. A standard seal flush line and throttle bushing protect the mechanical seal. SKS SelfSensing versions provide integrated variable-speed control and ProBalance® balancing; optional ECM packages improve energy efficiency.

KS sizes: 1½–14 inches.
KS performance: 40–12,500 GPM; 10–380 ft head; ¾–600 HP, depending on model.
Working pressure: Standard 175 PSIG (1,210 kPa); optional 300 PSIG (2,070 kPa), subject to pressure–temperature limits.
Fluid temperature: Standard 250°F (120°C); cooled seal flushing recommended above 225°F and required above 250°F.
Connections: Equal-sized suction/discharge ports with ANSI Class 125 flanges; optional Class 250.
Casing: Cast iron; ductile iron casing for Class 250 construction.
Impeller: Bronze or stainless steel, depending on construction.
Shaft: Type 416 stainless steel.
Coupling: Precision 6061-T6 aluminium split coupling.
Seal: Ceramic/EPT standard; optional tungsten carbide or silicon carbide.
Seal protection: Standard copper/brass flush line and bronze throttle bushing.
Service provisions: Suction/discharge pressure taps, casing drain and drilled mounting holes.
Options: Bronze wear ring, ductile iron support stand, external seal, 5-micron filter and cyclone separator.
SKS controls: Constant flow, constant pressure, flow compensation and duplex alternation; no-flow/dry-run alerts with optional shutdown.
ECM package: 3–10 HP, 1,750 RPM, 230/460 V, three-phase, 60 Hz; TEFC motor with required variable-frequency drive.
eLink™: NFC access to equipment documentation and support.

Small footprint suits restricted mechanical rooms.
Seal replacement requires no motor removal or piping disconnection.
Balanced axial loads extend bearing life.
Efficient impellers and low NPSH requirements support reliable operation.
Seal flushing reduces wear and leakage-related downtime.
Optional SelfSensing and ECM packages reduce balancing effort and energy consumption.
