HPKK400 High-Pressure Peristaltic Pump
The HPKK400 is a high-pressure peristaltic pump designed for controlled liquid transfer in medical instruments and other OEM equipment. Its four-roller pump head, quick tubing replacement and multiple motor configurations support different requirements for flow, pressure and control.
Because the liquid contacts only the tubing, the pump provides an isolated fluid path and simplifies fluid-contact material selection.

Pressure Configurations
Pressure performance depends on tubing size, motor configuration and operating speed. The manual provides reference pressure curves at 200 rpm for:
Actual flow decreases as outlet pressure rises. The required flow and pressure combination should be verified under the intended operating conditions.

Tubing Options
Standard Tygon E-3603 tubing is available in 14# and 16# sizes. Perx MED55 tubing in the same sizes is also listed as an available option.
Tubing standards and compliance apply to the tubing material rather than the complete pump or end equipment. Chemical compatibility, tubing life and regulatory suitability should be confirmed for the intended liquid and application.
Brushless Motor Control
The brushless motor configuration supports:
-
PWM speed control at 10–30 kHz with a 7.5 V amplitude
-
0–12% PWM duty cycle for stop
-
13–100% PWM duty cycle for speed adjustment
-
0–0.9 V analog input for stop
-
1–7.5 V analog input for speed adjustment
-
FG speed feedback
-
Forward and reverse rotation control
Reference flow data were measured using pure water at 20°C, standard atmospheric pressure and zero back pressure unless otherwise stated. Actual performance may vary with the liquid, tubing condition, outlet pressure, motor speed and duty cycle. Real-liquid testing is recommended before final OEM integration.
