MDC Series · Micro Dosing Pump Control Station & 1 ml – 10,000 ml/min

In quantitative filling, ratio-based conveying, and precision metering, inaccurate flow, cumbersome operation, and the high cost of attended operation have long been hidden bottlenecks holding back production efficiency. The Gear Pump Servo Control Box is built around precise, closed-loop servo control — making flow control simple, accurate, and intelligent.

Features: Precision metering · Compact size · Quantitative conveying · Modular pairing with JONSN-MR and MPG series pump heads

Composition: Servo motor + JONSN magnetic gear pump + communication control system

Dimensions: 310 × 200 × 240 mm

Operating & Applications

Operating Modes

① Sample Mode — continuous operation at a set speed; flow calibration and fixed-speed runs.
② Flow Mode — continuous conveying at a set flow rate (mL/min).
③ Speed Mode — cyclic quantitative dispensing by cycle count / interval / volume per sample.

Applications

Chemical batching and ratio-based conveying | Metered lubrication and cooling supply | Precision metering in food and pharmaceuticals | Laboratory and pilot-scale systems | Quantitative dosing of new-energy materials | Automated production line integration

img of JONSN Drum Pump Series

JONSN Drum Pump Series

Flow Rate:Up to 150 L/min (electric drive) / 80 L/min (pneumatic drive)

Head: Up to 25 m (electric) / 11 m (pneumatic), suitable for transferring liquids to elevated tanks and storage tank areas.

Speed: 0–10,000 rpm variable speed control, allowing flexible flow adjustment according to operating requirements.

Viscosity: 0–2,000 cP for standard models; up to 25,000 cP for high-viscosity applications.

Series: PT Big Flow, TB Small Caliber, HV Medium Viscosity, HT High Viscosity, and ZS Pneumatic Piston Pump.

ApplicationsIn industries such as chemicals, coatings, pharmaceuticals, and food processing, transferring drum-packaged liquids is one of the most frequent operations in daily production. Manual pouring is inefficient and prone to splashing and spillage, while corrosive, flammable, and explosive media introduce additional safety risks.JONSN Drum Pumps feature a direct-insertion design and a sealless structure. Simply insert the pump tube into the drum and start pumping. A standard 200L drum can be emptied in just 2–3 minutes, delivering fast, safe, and leak-free fluid transfer.
