Common Applications

The CP-PMD3COV-X is a PWM-controlled DDC-class water pump engineered for custom liquid cooling loops. It spins up to 5000 RPM, delivers a maximum head of 6 meters and a peak flow rate of 700L/H, which is sufficient to circulate coolant through a CPU block, one or two GPU blocks and a 360mm radiator on a single pump. The pump body uses ABS resin and PMMA, while the armored top is aluminum alloy that sits outside the coolant path. The top integrates a reservoir-ready outlet so it pairs directly with cylindrical reservoirs, and all ports use G1/4 threads. Power is supplied by a 4-pin Molex connector and speed is regulated through a separate 4-pin PWM header.

Frequently Asked Questions

Q: What are the rated flow and lift figures?

A: Maximum flow is 700L/H and maximum lift is 6 meters at full speed.

Q: How is the pump powered and controlled?

A: 4-pin Molex for 12V power and a separate 4-pin PWM header for speed control between roughly 10-15V input.

Q: What thread do the inlet and outlet use?

A: G1/4 inch BSP threads on both inlet and outlet.

Q: Is the aluminum top in contact with the coolant?

A: No. The aluminum armor sits outside the wetted path, so the loop remains all-copper/brass/acetal compatible.

Q: Can it directly mount a reservoir?

A: Yes. The top is reservoir-ready and pairs with Bykski PMMA tube reservoirs such as the 60mm and 150mm CT-series.
