If you are looking for a non-clog, pulse-free high-precision dosing pump to transfer high-viscosity fluids or particle-containing liquid for laboratory and industrial chemical processes, our dual plunger constant flow syringe pump is your ideal solution. Different from ordinary single-channel syringe pumps, this dual-syringe pump adopts alternating suction-injection design with ceramic reversing valve, realizing continuous zero-pulsation liquid output. It supports viscous & particle media transfer without blockage, with ultra-high flow accuracy, multiple operation modes and humanized touch control, widely used in pharmaceutical, chemical, food, environmental testing and chromatography analysis industries.
The core dual-syringe alternating transmission structure matches high-speed ceramic reversing valve, achieving continuous liquid delivery with absolutely no flow pulsation. Specially optimized flow channel structure smoothly transports high-viscosity raw materials and liquid with tiny solid particles, effectively solving clogging problems that plague traditional metering pumps. The valve switching time is less than 0.2s to guarantee stable, seamless fluid output during long-time running.
This dual plunger pump owns ultra-stable flow control performance: flow accuracy error ≤0.9%, repeatability error between 2‰~5‰. Equipped with precise lead screw transmission, single-step piston moving distance only 0.005mm. The control resolution reaches 0.1ul~1ul matching 1.0ml to 25ml interchangeable syringes, built-in intelligent calibration function to maintain long-term consistent dosing precision for strict laboratory and chemical dosing processes.
Four independent working modes are integrated to cover all common fluid delivery scenarios: continuous transmission, fixed-volume metering, timed fixed-volume injection and timed start-stop control. Users can freely set flow rate, output volume and working cycle via touch panel, suitable for batch sampling, constant reaction feeding, timing analysis and other complex lab production workflows.
Adopt 4-inch industrial true-color LCD capacitive touch screen with synchronous animation simulation of fluid running status, all parameters visible and adjustable at a glance. Silent internal drive structure avoids mechanical noise interference, perfectly fits quiet laboratory testing environments. The outer shell uses 304 plastic-sprayed stainless steel, corrosion-resistant and easy to wipe clean after chemical liquid splashing.
All wetted parts adopt chemical-resistant premium materials: high borosilicate glass syringe tube, PTFE piston, stainless steel push rod and ceramic reversing valve. The pipeline interface is standard 1/4-28UNF internal thread for quick pipeline assembly. Max liquid circuit bearing pressure reaches 0.68Mpa, stable piston driving force ≥80N to push thick high-viscosity medium smoothly.
Supports interchangeable syringes of 1.0ml, 2.5ml, 5.0ml, 10ml and 25ml to meet micro to medium flow dosing needs. Applicable working temperature ranges from 5℃ to 55℃ with relative humidity below 80%, adaptable to constant temperature labs, chemical workshops and environmental monitoring stations without extra environmental modification.
This dual plunger constant flow pump serves multiple precision fluid fields: pharmaceutical chemical dosing, liquid composition analysis, environmental monitoring testing, medical laboratory analysis, chromatography instrument supporting equipment, food ingredient delivery and new material lab research. It replaces traditional gear pumps, peristaltic pumps and single syringes for scenes requiring stable, particle-adaptable and pulse-free fluid supply.
