# Industrial Specification: Pump Power End

## 1. Technical Definition
The mechanical assembly that converts rotational input power into reciprocating motion to drive the fluid end of a mud pump.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **50-5000 kW at 60-1200 rpm**. Failure boundary: **Crankshaft deflection exceeding 0.15 mm/m at 5000 kW load**, Mechanism: **Bending fatigue failure due to alternating stress exceeding 345 MPa yield strength of ASTM A36 steel under cyclic loading at 1200 rpm**.

### 2.1 Analytical Physics Model
Governed by the **Darcy-Weisbach Pressure Drop**:

> **Primary Equation**: $\Delta P = f \cdot \frac{L}{D} \cdot \frac{\rho v^2}{2}$  
> **Engineering Impact**: Critical for sizing CIP (Clean-In-Place) pump heads.
