High-quality Machining
How JONSN Standardizes DP Multi-Order Volumetric Reproducibility? Clearances locked via world-class CNC centers, 100% full-process certified via premium Dutch-imported mass flow meters.
Onsite Heavy Machining Infrastructure
DP series micro-casings and ultra-clean fluid blocks are flawlessly carved by onsite Japanese Mazak Multi-Axis CNC Machining Centers and Tsugami CNC lathes. Clearance boundaries are rigidly locked within micro-levels using automated plane lapping to eliminate manual deburring errors and random hand-fitting variance, steering the volumetric efficiency of the two-stage sealed shell toward perfection.

FAQs aboutJONSN DP Series High-precision Gear Metering Pump Series

How does JONSN DP series ensure high linearity and pulse-free uniform flow as an elite gear metering pump platform?

Legacy reciprocating plunger pumps or pneumatic diaphragm water pumps create severe fluid stroke transient pulses and pressure oscillations, ruins coating reproducibility and thickness consistency. JONSN DP series high-precision metering gear pump adopts

What specialized surface treatments allow JONSN gear dosing pump loops to safe resist intensive wear from micro-particle fillers?

Handling medium-to-high viscosity fluids filled with sub-particle fillings or abrasive coloring agents can cause premature internal gear profile scratching and leakage bypass decays. JONSN DP series gear dosing pump structures undergo high-strength therma

Can the JONSN DP heavy-duty high viscosity pump block thoroughly handle super thick adhesives up to 500000 MPa·s under high counterpressures?

Yes. As calibrated in our technical reference documents, JONSN DP series high viscosity pump platform yields an expansive viscosity capacity ranging from 100 up to 500000 MPa·s. Carved seamlessly out of premium 440B hard-tooth steel or high-rigidity Alloy

What dynamic motor integration options and flexible assembly layout models are accessible within this precision metering pump series?

To fulfill diverse system simplification parameters, JONSN DP series supports flexible dynamic motor integrations and mechanical layout co-designs. Engineers can select among AC asynchronous reduction motor horizontal installation layouts, L-type servo/st
