## 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.

### 3-in-1 Integration

Combines a D5 pump, 120ml reservoir, and coolant distribution manifold in a single bracket-mounted unit, simplifying loop assembly for compact single-GPU or single-CPU systems.

### Genuine D5 Pump

PWM-controlled D5 pump delivers up to 3.9m pressure head and 1500 L/h flow, with a 20–100% PWM duty cycle range for noise-optimised operation.

### QDC Drain Port

Dedicated drain port with Quick Disconnect Coupling enables fast, tool-free system draining for maintenance and component upgrades without full loop disassembly.

### 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.
