XBD-HL constant tangent vertical fire pump Product Category: Diameter: Φ50-Φ200 (mm) flow: 5-80L / S head: 30-230 (m) Applicable medium: water Introduction I. Overview: XBD-HW Series Horizontal constant tangent when fire pump, also known as tangential pump with variable flow regulator characteristics, namely in the whole flow range, head changed little, the pump maximum flow rate range from zero to the desired flow, its head changes within 5% range, and low flow or zero flow without over-pressure, thus avoiding the ordinary centrifugal flow at fire scene small overpressure large flow of water is not on the phenomenon. Greatly improving the safety and reliability of fire-fighting and fire-fighting equipment efficiency and firefighters. According to constant tangent fire pump its own characteristics, combined with our company's specific circumstances, for 75kW or less (including 75kW) of constant pressure fire pump is a horizontal, vertical structure, 75kW more than just horizontal structure. Plus the long axis of the whole series are direct-Y-type motor, eliminating couplings. Compact pump structure, nice, small, reliable mechanical seal, which greatly improves the reliability of water pump; pump impellers are open, the axial force is small, no mouth ring, will eliminate the rust killed, so the whole pump system running smoothly, low noise, long life, easy maintenance. Pump cover made of cast iron, ductile iron impeller bronze material or according to user requirements. Second, the performance: Horizontal constant tangent fire pump working conditions: speed 1450 / 2900r / min (motor synchronous speed) medium temperature: room temperature water flow range: 0 ~ 80L / S lift range: 30 ~ 260m motor power: 15 ~ 160KW three main purposes: XBD-HW Series Horizontal tangent constant pressure fire pump is mainly used for industrial, civil buildings fixed firefighting systems (fire extinguishing system, automatic sprinkler system and spray system) of water, the other can also be used Fire and life (production) sharing and building water supply system, municipal, industrial, boiler feed water and other occasions. Horizontal constant tangent fire pump body made of cast iron, other flow components specific needs of stainless steel, bronze or other anti-corrosive material manufacture according to user.
