3-in-1 Pump, Reservoir, and Manifold for Compact Loops
The EK-Pro Pump Reservoir Manifold X3 D5 - Acetal is a versatile 3-in-1 unit serving as a pump, reservoir, and manifold. With eight G1/4" ports and a genuine PWM-controlled D5 pump, it offers exceptional performance and reliability while maintaining low noise levels.
Featuring a drain port with a Quick Disconnect Coupling for easy system maintenance and durable construction with Black POM acetal and stainless steel components.
Three design decisions worth calling out
Genuine PWM D5 Spherical Motor
The electronically commuted spherical motor D5 pump delivers up to 3.9m pressure head and 1500 L/h maximum flow, with PWM speed control from 20–100% duty cycle for quiet operation at partial loads.
Pre-Defined Loop Connections
Six of the eight G1/4" ports are pre-configured for one CPU water block, one GPU water block, and one radiator, with dedicated fill and QDC drain ports simplifying initial loop build and ongoing maintenance.
Black POM Acetal + Stainless Steel
Primary reservoir body in black POM acetal with stainless steel components, ABS, EPDM seals, and acrylic viewing panel ensures long-term chemical compatibility and visibility of coolant level.
