high pressure resistant pump

With the continuous tightening of domestic environmental policies, large-scale implementation of industrial wastewater resource recovery, high-salinity wastewater reduction, and zero liquid discharge (ZLD) projects has been achieved. Currently, zero liquid discharge and high-salinity wastewater resource recovery projects are widely adopted across industries such as landfill leachate, lithium battery new materials, fine chemicals, and dyeing and electroplating. Core processes like MBR+DTRO reverse osmosis and concentrated water evaporation crystallization are commonly employed. Within the entire system, high-pressure booster pumps serve as the core power equipment.   Traditional water pumps often face industry challenges such as high salt corrosion perforation, high-pressure leakage, pressure fluctuation damage to membranes, high frequency of operation and maintenance, and high energy consumption, which directly affect the stability and operating costs of the entire water treatment system.   Nanyuan Pump Industry is deeply engaged in the research and development of high-pressure fluid equipment. In response to complex and demanding industrial wastewater conditions, Nanyuan Pump Industry has exclusively developed three series of special stainless steel high-pressure multi-stage centrifugal pumps, HSP, MHP, and MHPD. With gradient anti-corrosion materials, stable high-pressure performance, and long-term energy-saving operation and maintenance advantages, Nanyuan Pump Industry accurately adapts to the full scenario needs of DTRO high-pressure boosting, concentrated water feeding, deep desalination, etc., providing a one-stop reliable high-pressure fluid solution for zero discharge industrial wastewater projects.       Full matrix product layout, covering large, medium, small, full flow high-pressure working conditions   The differentiated layout of Nan Yuan's three major series of high-pressure pumps takes into account site limited small-scale projects, conventional DTRO projects, and centralized zero emission projects in large industrial parks, with on-demand selection and precise matching to eliminate equipment performance overcapacity or mismatched operating conditions.   1.HSP vertical high-pressure multi-stage centrifugal pump | Optimal selection for small working conditions and compact layout     HSP high-pressure pump is equipped with a permanent magnet ultra efficient first stage energy efficiency motor.

Self balancing hydraulic structure, long-term stability and high pressure resistance All high-pressure models in the series adopt an axial force self balancing design, effectively offsetting the axial thrust generated by high-pressure operation and significantly reducing the wear of impellers and bearings. Paired with high-precision matching bearings, it can meet the continuous operation needs of the water treatment industry all year round, greatly improving the service life of the equipment.   3. The low-pressure area design of the front-end machine seal significantly reduces the probability of leakage Innovative mechanical seal layout structure allows the sealing components to work in a low-pressure environment, avoiding the problem of continuous impact of high-pressure media damaging the sealing components, effectively reducing mechanical seal leakage failures, prolonging the replacement cycle of vulnerable parts, and reducing the frequency of shutdown maintenance.   4. Smooth fluid output, effectively protecting the back-end membrane system Optimize the hydraulic model, with continuous and smooth flow and pressure output, no pulses, and no significant fluctuations, to avoid water hammer impact damage to the sealing structure of the DTRO membrane stack, reduce membrane element fatigue loss, and help reduce the cost of replacing consumables for the entire system.   5. IE5 ultra efficient frequency conversion configuration, long-term energy saving and consumption reduction The main models are equipped with IE5 top-level energy-efficient permanent magnet variable frequency motors, which can dynamically adjust speed according to system load and water inlet conditions, avoiding energy waste caused by the "big horse pulling small car" of power frequency pumps. Long term operation has significant energy-saving effects and effectively reduces project operating energy consumption costs.   6. Modular and minimalist structure, convenient and worry free operation and maintenance Modular design of the whole machine, strong universality of components, few categories of vulnerable parts, and convenient procurement of spare parts. The disassembly and maintenance process is simple and does not require complex procedures, greatly reducing the manpower and material investment in later operation and maintenance.   Full scene adaptation, deeply cultivating the field of zero discharge of industrial wastewater   Relying on excellent corrosion resistance and stable high-pressure output capability, the three series of high-pressure pumps are widely adapted to harsh working conditions in multiple industries: • Landfills and incineration plants: leachate DTRO high-pressure transportation, concentrated water pressurization • Chemical, printing and dyeing, electroplating industries: zero discharge of high salt wastewater, deep desalination system • Lithium battery and new materials industry: concentration and reduction of production wastewater, high-pressure reverse osmosis system • Industrial Park: Centralized wastewater treatment, reclaimed water reuse, front-end feed pressurization for evaporation crystallization   Brand strength, customized empowerment project implementation   With the continuous upgrading of environmental control standards, zero wastewater discharge projects have increasingly stringent requirements for equipment corrosion resistance, stability, and low operation and maintenance costs.
