The Aryung ASPK 4-19/10 is a 1.1 kW compact stainless steel multistage immersion pump for machine tool coolant systems, with 10 impeller stages in 19 chambers. The ASPK series is a high-pressure multistage centrifugal pump with a compact build for machines where installation space is limited. Wetted parts are stainless steel and the mechanical seal uses FKM, so it holds up to heat and long run times. Typical uses: CNC lathes, machining centers, grinders, parts washers and filtration systems.

60 Hz build. This listing is for 60 Hz power, the standard in the US. The 50 Hz version of a given model can use a different motor and stage count.

Built to order: this model is made by Aryung in Korea and ships in about 30 days. Request a quote for price and lead time, or call 847-466-5459.

Use

  • Fluid must be clean and low viscosity, free of solid particles, abrasive sludge and fibers, and not explosive.
  • If the fluid is heavier or thicker than water-soluble coolant, the motor may need to be upsized.
  • Immersion depth can be extended with empty chambers. More empty chambers lowers the pressure.
  • Fit a baffle between the discharge and suction sides of the tank so returning chips and air are not pulled straight back in.

Read the curve for 10 stages. Curves are based on ISO VG 2 (2 cSt) fluid at 20°C.

Model number guide

ASPK = series, 4 = standard flow (4 m³/h), 19 = number of chambers, 10 = number of impeller stages. Codes follow for the seal material (SC, ST or TT) and voltage (2/2 = 200/220 V, 2/3 = 220/380 V, 4/4 = 415/440 V).
