Product Overview:

The XBD-DL series fire pumps are a new product independently developed by our company in response to domestic market demand and the specific operational requirements for fire‑fighting applications. Rigorous testing has demonstrated that this series fully meets the performance criteria stipulated in current fire‑protection codes and national standards for fire‑water supply systems. This line of fire pumps fills a critical gap in the domestic market, with overall performance reaching the advanced international standards of comparable products from the 1990s. Mobile pump trucks and self‑priming pump trucks.

The XBD‑DL series fire pumps are designed using advanced technologies and manufactured from high‑quality materials. They feature exceptional reliability—preventing the common issue of pump seizure upon restart after prolonged inactivity—along with high efficiency, low noise, minimal vibration, extended service life, flexible installation options, and convenient maintenance. This series offers a broad operating range, with a flat flow‑head curve; the ratio of the shutoff head to the design head is less than 1.12, resulting in closely spaced pressure stages that facilitate pump selection and energy savings. All models have been rigorously tested by the National Fire Equipment Quality Supervision and Inspection Center, and their performance fully complies with the national standard GB 6245‑1998 “Performance Requirements and Test Methods for Fire Pumps,” reaching the advanced level of comparable domestic products.

General Data

The XBD-DL series pumps, while meeting fire‑fighting service requirements, also accommodate domestic (and industrial) water supply needs. This product can be used in standalone fire‑fighting systems, as well as in combined fire‑fighting and domestic/industrial water‑supply systems, and is suitable for applications such as building, municipal, industrial and mining water supply, and boiler feedwater. Air filter; chemical dosing unit.

Operating parameters:

Rated flow rate Qn = 5 L/s – 100 L/s

(18 m³/h–360 m³/h)

Rated pressure Pn = 0.30 MPa – 2.39 MPa

(Head: 29 m–239 m)

Rotational speed n = 1450 r/min – 1480 r/min

Pump inlet pressure Po ≤ 0.2 MPa

Scope of Use:

The XBD-DL series pumps are suitable for conveying clean water or liquids with physicochemical properties similar to water, provided they contain no solid particles and have a temperature not exceeding 130°C, as well as mildly corrosive liquids.

This series is primarily used for water supply in fixed fire‑protection systems—such as fire hydrant systems, automatic sprinkler systems, and water‑mist fire‑extinguishing systems—in both industrial and civil buildings.
