LVR (S) series vertical multi-stage centrifugal pump

LVR (S) series vertical multi-stage centrifugal pump uses:

LVR（S）The series of vertical multi-stage centrifugal pumps are mainly suitable for conveying liquids with low viscosity, non flammable and non explosive, easily vaporized, and free of solid particles and fibers.

Water supply: high-rise building water supply and drainage, water plant filtration and transportation, main pipeline pressurization;

Industry: flushing and cleaning systems, boiler feedwater, cooling water circulation, water treatment systems, equipment supporting systems;

Water treatment: ultrafiltration system, reverse osmosis system, distillation system, separator, swimming pool;

Agricultural irrigation: sprinkler irrigation, drip irrigation;

Food and beverage industry;

Fire protection system;

Product features:

Compact structure, beautiful appearance, high efficiency, low noise, reliable sealing, and easy use and maintenance.

Operating conditions:

Low viscosity, non flammable and non explosive liquid that is prone to gasification, and does not contain solid particles or fibers. The liquid cannot undergo chemical reactions with the pump material. When the density and viscosity of the transported liquid are greater than water, a high-power motor is required.

Introduction to Pump Parameters

Pump flow rate Q

Flow rate is the amount of liquid (volume or mass) that a pump delivers per unit of time.

The volumetric flow rate is represented by Q, with units such as m3/s, m3/h, l/s.

Pump head H

Head is the increase in energy per unit weight of liquid pumped by a water pump from the pump inlet flange to the pump outlet flange. That is to say, the effective energy obtained by a Newtonian liquid through a pump. Its unit is N · m/N=m, which is the height of the liquid column pumped by the pump, commonly referred to as meters.

Pump speed n

The rotational speed is the number of revolutions per unit time of the pump shaft, represented by the symbol n, and the unit is rpm or r/min.
