The SC2301CPW is a 24V peristaltic pump for 3D printer liquid cooling and fluid handling, rated at ≥100 mL/min flow, 40–150 kPa working pressure, ≤60 dB noise at 50 cm, and ≤200 mA current draw. If heat creep keeps jamming your hotend or manual resin refills keep ruining overnight prints, this pump solves both problems with one reliable, low-maintenance design. Because the SC2301CPW is a peristaltic pump, liquid flows only through the tubing - the pump body never touches the fluid, so there are no seals to wear and nothing to leak. This guide covers the SC2301CPW parameters, its role as a peristaltic pump for water cooling hotends, and how it compares with a micro gear pump alternative.
Why Your 3D Printer Needs a Reliable Fluid Pump
Heat creep is the leading cause of otherwise inexplicable FDM jams. Inside a sealed chamber at 45–55°C, fans simply recirculate warm air, filament softens above the melt zone, and the nozzle clogs mid-print. SLA machines fail differently: a resin shortage at 3 a.m. leaves a visible layer line or scratches the FEP film. Both failure paths trace back to the fluid loop, and Skoocomtech's engineers put it plainly - the circulation system is just as critical as the extruder or motion platform.

SC2301CPW Parameters: What the Numbers Mean
Flow rate: ≥100 mL/min
A single hotend loop needs only 20–50 mL/min, so the SC2301CPW's guaranteed minimum gives real headroom - enough for dual-hotend machines and for faster fluid turnover in resin and cleaning duty. In a resin refill system, a 50–100 mL top-up takes roughly 30–60 seconds, with no overfilling.
Pressure: 40–150 kPa
Working pressure is what pushes fluid through narrow tubing, quick-disconnect fittings, and cold-plate micro-channels. Because a peristaltic pump is positive displacement, flow stays consistent even as system resistance rises - the pump does not stall when the loop tightens.
Noise: ≤60 dB at 50 cm
Measured at arm's length, the SC2301CPW is a low noise pump for 3D printer use - about the level of a normal conversation and often quieter than the printer's own stepper motors. For a bedroom or shared office, that is a genuine quality-of-life win.
Power: ≤200 mA at 24V
At 24 V, ≤200 mA means under 5 W of power and minimal heat inside the enclosure. You can drive the pump directly from a printer mainboard or a MOSFET-controlled port - no extra power supply, no voltage conversion.
No Seals, No Leaks: Why the Peristaltic Design Wins
The SC2301CPW works by squeezing a flexible tube with rotating rollers. Liquid moves only inside that tube, so the pump body's mechanical parts never contact the fluid - no rotating shaft seal, no leakage path, and no contamination of the coolant or resin. That single trait explains the pump's long-life behavior in 3D printing: after years of continuous water cooling, the only part that can wear is the tube, and replacing it takes about two minutes. The design also self-primes and tolerates small bubbles and particles without stalling, which simplifies filling and bleeding a new loop.
Three Applications for One 24V Peristaltic Pump
Hotend liquid cooling
For a hotend cooling pump loop, water carries about four times the specific heat of air by mass, so liquid removes far more heat per unit of flow than any fan - and an external radiator dumps that heat outside the chamber. In field reports from Skoocomtech, switching a hotend to water cooling stabilized temperature from ±5°C swings to ±1°C or less and lifted print success rates from roughly 70% to over 90%. The SC2301CPW 3D printer cooling performance covers this duty with margin.
Automated SLA resin refill
Paired with a photoelectric level sensor and a small controller, the SC2301CPW becomes an automated resin dispensing pump: it tops the vat up by 50–100 mL whenever the level drops, so prints run unattended overnight. Resin touches only the tubing, so there is no cured-resin cleanup inside the pump - the definition of low-maintenance.
Cleaning fluid circulation
Print heads, nozzles, and UV-curing systems need periodic rinse cycles. The pump self-primes from a cleaning tank and meters rinse fluid at a consistent rate, flushing debris without splashing. Keep the fluid compatible with the tubing - distilled water, purpose-made coolant, or mild cleaning solutions.

SC2301CPW FAQs
Is the SC2301CPW a gear pump or a peristaltic pump?
It is a peristaltic pump. The liquid flows only inside the tube, so the pump body has no seals and cannot leak - a common point of confusion because both types are positive displacement.
Can I run it directly from my printer mainboard?
Yes. It is a 24V peristaltic pump drawing ≤200 mA (under 5 W), which most mainboard outputs handle easily. Confirm the MOSFET rating before wiring.
How long does the tubing last?
In coolant duty, good silicone tubing lasts thousands of hours; in resin service, expect months to a year. When the tube feels soft or flat, swap it - replacement tubing costs pennies.
What fluid should I use?
Distilled water with a biocide, purpose-made coolant, or mild cleaning solutions. Avoid aggressive acids and abrasive fluids that could damage the tubing.
