The product's brand is Jiayu, model XBD5.0/15-80-200L15kw, material cast iron, performance fire protection, head 50(m), specification XBD5.0/15-80-200L, excluding tax and shipping.

Next, we'll introduce measures to enhance the anti-cavitation performance of fire pumps. Materials with higher strength, hardness, and toughness exhibit better chemical stability and stronger anti-cavitation properties. During the design phase, employing a slightly larger impeller inlet angle and area can reduce bending and blockage at the inlet, but caution must be exercised not to make the angle too great, as this may impact efficiency. Under conditions aimed at improving high flow rates, these adjustments help to minimize flow losses.

Product Overview
The xbd-l type fire pump is available in two types: single suction single stage and single suction multi-stage segmented. It is designed for conveying clear water without solid particles and liquids with physical and chemical properties similar to water. Mainly used for fire hydrants, sprinklers, pressure maintenance, etc. The flow rate range of the liquid conveyed is 0.42-333l/s, the pressure range is 0.8-2.25mpa, the matching power range is 0.18-160kw, and the diameter range is φ15-400mm.
The default colors are: Fire Red for fire safety and Blue or Black for potable water.

Firstly, we'd like to introduce measures to enhance the effective NPSH (Net Positive Suction Head) of the fluid intake system. Operators can improve the NPSH of the intake system by reducing the installed height of the pump, increasing the pressure of the liquid level in the fore tank before the pump, converting the upward intake to a backflow setup, and minimizing flow losses in the piping before the pump, thereby reducing the occurrence of cavitation.
