Piston Water Small Hydraulic Pump Dosing 2-4900 L/h 10 Bar

The Piston Water Small Hydraulic Pump Dosing 2-4900 L/h 10 Bar is a compact piston-type hydraulic dosing pump that delivers precise, adjustable flow from 2 to 4,900 liters per hour at up to 10 bar pressure. Its piston design gives stable, low-pulse dosing, long service life and simple maintenance. Driven hydraulically, it works well where electric drives are impractical or where a robust, high-pressure metering solution is needed.

Usage scenarios (three short sentences):

Ideal for water and wastewater treatment to dose chlorine, coagulants, flocculants and pH control chemicals, and for industrial boiler feed and cooling-water chemical dosing. Useful in agriculture and horticulture for fertigation, nutrient or pesticide injection and precise liquid feeding in greenhouses. Also suited to aquaculture, mining, construction (admixture dosing) and remote or hazardous sites where a hydraulic drive is preferred over electric motors.

    High-Precision Compact Dosing Pump

    This Chemical Dosing Pump is a piston small hydraulic pump delivering 2–4900 L/h flow, up to 10 bar discharge pressure, a 10:1 turndown and ±2% stability accuracy, with a 3 m suction lift, 45°C max liquid temperature and capability to handle viscosities up to 1200 cP. Designed for water and industrial treatment tasks such as pH adjustment, flocculation, polymer dosing, hypochlorite disinfection and dye handling, it offers precise metering, leak-resistant operation via a special valve seat and self-cleaning check valves, and configurable pump heads for high-viscosity, pulp or corrosive media. Robust structural features include variable eccentric stroke adjustment, sliding bearings and high-strength worm gear for low pulsation and long-term stability, multiple control options (manual, electric stroke controller or frequency inverter with 4–20 mA I/O) and a selectable liquid end of PP/PVC/PVDF/316SS with PTFE diaphragm and glass/ceramic/316SS check balls.

    Small High-Pressure Dosing Pump 

    The Piston Water Small Hydraulic Pump is a versatile Chemical Dosing Pump for municipal tap water, swimming pools, urban sewage and industrial effluent, delivering 2–4900 L/h at up to 10 bar with stability accuracy of ±2% and a 10:1 turndown ratio. It handles liquids up to 45°C and viscosities up to 1200 cP, with PTFE diaphragms, interchangeable liquid end materials (PP, PVC, PVDF, 316SS), glass/ceramic/316SS check balls, self-cleaning valves and specially sealed seats to prevent leakage. Adjustable stroke control is available manually, via electric stroke controller (4–20 mA) or frequency inverter, while robust worm gears, sliding bearings and variable eccentric stroke minimize pulsation for stable long-term operation.

    Precise Powerful Durable Efficient

    Built with decades of fluid-handling expertise, the Piston Water Small Hydraulic Pump Dosing 2-4900 L/h 10 Bar is engineered for precise, reliable metering in demanding environments. As a compact Chemical Dosing Pump it delivers adjustable flow from 2 to 4900 L/h at up to 10 bar, offering stable piston actuation, corrosion-resistant wetted parts, and low pulsation for accurate chemical feed and minimal maintenance. Key advantages include high-pressure capability for long pipe runs, an energy-efficient hydraulic drive, simple calibration and serviceability, and robust materials for extended life in industrial, water treatment, and process dosing applications.

    Material introduction

    The Chemical Dosing Pump features corrosion-resistant liquid end options—PP and PVC for general service, PVDF and 316 stainless steel for aggressive or high-purity media—paired with a PTFE diaphragm for strong chemical and thermal resistance. Ball check valves come in glass, ceramic or 316SS and a specially designed valve seat with a self-cleaning check structure minimizes leakage and fouling across demanding chemistries. These material selections, combined with a robust drive unit and high-viscosity-capable pump head, ensure reliable metering up to 10 bar while handling temperatures to 45°C and viscosities up to 1200 cP.

    FAQ

    1
    What kinds of applications is the Piston Water Small Hydraulic Pump Dosing 2–4900 L/h 10 Bar best suited for?
    It is designed for precise metering and continuous dosing of water and water-based fluids in applications such as water and wastewater treatment, fertigation and agricultural injection, chemical dosing (pH control, biocides), boiler water treatment, and small industrial process lines where flows between 2 and 4,900 L/h and pressures up to 10 bar are required.
    2
    What are the pump’s key performance limits and how is flow adjusted?
    The pump delivers between 2 and 4,900 L/h with a maximum discharge pressure of 10 bar. Flow is normally adjusted by changing stroke length and/or drive speed (frequency) or by built-in adjustment mechanisms if supplied. Actual dosing accuracy and the achievable turndown depend on the drive, control settings, and piping arrangement.
    3
    What liquids can I safely dose with this pump?
    It is suitable for water and most water-based solutions (fertilizers, dispersions, dilute acids/bases, many industrial chemicals). Compatibility with aggressive or highly viscous fluids, solvents, or abrasive slurries depends on the pump’s wetted materials and seals—check the manufacturer’s materials compatibility chart before use. Solids and highly abrasive fluids are generally not recommended.
    4
    What are the basic installation and commissioning steps for reliable dosing?
    Mount the pump securely and level, connect suction and discharge lines using pressure-rated fittings, install a suction strainer/foot valve and a discharge pressure gauge, and fit a pulsation dampener and check valve if required. Provide a pressure relief or bypass to protect against overpressure. Prime the suction line and bleed trapped air before starting. Adjust stroke and speed gradually while monitoring flow and pressure, and verify dosing with a calibrated meter.
    5
    What routine maintenance is required and how do I troubleshoot common problems?
    Regular maintenance includes inspecting and replacing seals, packings or valves as wear items; cleaning or replacing suction strainers and filters; checking fittings for leaks; and ensuring any drive system lubrication is maintained. Common issues: air in suction (causes loss of flow) — re-prime and check seals/foot valve; reduced flow — inspect for clogged suction/discharge lines or worn valves; excessive pulsation — install or service dampener; leakage — tighten/replace seals and fittings. Follow manufacturer service intervals and keep spare wear parts on hand.
    6
    What safety and operating precautions should I observe?
    Never exceed the 10 bar maximum discharge pressure and always use pressure-rated piping and fittings. Fit a pressure relief or bypass valve and a pressure gauge on the discharge. Avoid dry-running the pump unless specified as safe by the manufacturer. Use appropriate personal protective equipment when handling chemicals, and ensure the pump materials are compatible with the chemical being dosed. For any electrical or hydraulic drive connections, follow relevant wiring/hydraulic safety standards and the manufacturer’s installation manual. For specific temperature ranges, materials, and detailed limits, consult the product datasheet or supplier.
