Sofo NP series miniature magnetic gear pumps have the characteristics of no leakage, small flow, high pressure, wide temperature range, can transport low and medium viscosity and gas-liquid two-phase liquids, can be dry running, self-priming ability, the flow rate is little affected by the pressure, and the control accuracy can be up to 0.3%, and so on.
This series of low-pressure spray gear pumps with its precise control, no leakage environmental protection, small flow and high pressure, corrosion resistance and long life, ultra-low energy consumption and economy and other characteristics, significantly improve the quality of the crop and planting efficiency, while reducing environmental risks and operating costs, so that the series of energy-saving miniature spray pumps in a lot of vegetable greenhouse spraying system has been widely used.
Precise environmental control
Uniform spraying
The spray pump can precisely regulate the size of atomized particles of water, pesticide or nutrient solution to ensure uniform coverage, avoid localized over-wetting or drought, and enhance the consistency of crop growth.
Magnetic gear pumps have a stable flow rate (e.g. NP1700 with a flow rate of 1700 ml/min), and the pulsation-free feature can be matched with a flow meter to realize high-precision closed-loop control and ensure uniformity of spraying.
Ultra-low energy consumption design
Low-pressure spraying system (10~20bar), compared with high-pressure system, energy saving more than 30%.
Magnetic gear pump frequency conversion energy-saving function (such as NP series) can reduce energy consumption by 35%, and at the same time through the self-priming height (dry suction range of 4 meters) to reduce the waste of water resources, especially suitable for water-scarce areas greenhouses.
Reliability Guarantee
Leak-free design
The adoption of magnetic drive technology (e.g. NP series) completely eliminates the risk of mechanical seal leakage.
Corrosion resistance and long life
The pump body material can be selected from 316L stainless steel, PEEK and other corrosion-resistant materials, and the gears are made of self-lubricating engineering plastics, so that pesticides or nutrient solutions containing corrosive components can be transported for a long time.
The service life in clean media is over 20,000 hours, which significantly reduces the maintenance frequency and cost.
Operation friendliness
Supports customization of material, pressure, flow rate and other parameters (such as explosion-proof motor adaptation) to meet the refined needs of different greenhouse sizes or special crops (such as high value-added fruits and vegetables).
Economy Enhancement
Low-pressure energy-saving economy
10~20bar low-pressure spraying: no need to lay high-pressure piping and nozzle systems, construction costs reduced by 40 percent
Low energy consumption: frequency conversion speed control + magnetic drive technology, comprehensive energy consumption is 35% lower than other pumps
Dry running capacity: NP series dry running up to 100 hours, reducing the risk of damage from idling, avoiding downtime losses
