Chemical Industry Technical FAQ
How does a JONSN chemical process gear pump eliminate toxic fugitive emissions under high backpressure?
Conventional chemical pumps use mechanical shaft seals that wear down and leak hazardous vapors under high backpressure. A JONSN chemical process gear pump (such as the MRC/MRE series) utilizes a hermetically sealed magnetic drive pairing static O-ring containment shells with solid-carved 316L or Hastelloy C-276 housings. Holding continuous differential pressure up to 25–50 bar and static pressure up to 4–6 MPa, it encloses corrosive media 100%, completely eliminating fugitive emissions across chemical precision dosing applications.
What metallurgy and magnetic coupling advantages make JONSN a premier petrochemical magnetic drive pump?
Petrochemical refining loops handle aggressive catalysts and hot hydrocarbons at elevated pressures. JONSN petrochemical magnetic drive pump units feature Mazak 5-axis CNC carved Hastelloy C-276 housings, nanostructural Zirconia ceramic shafts, and modified PEEK composite ceramic bearings. Powered by high-grade NdFeB permanent magnets through non-magnetic shells, it prevents dynamic slip-heating and demagnetization under 50 bar pressure spikes, delivering verified 20,000 hours maintenance-free service life.
Why is JONSN surface treatment electroplating pump technology superior for micro-dosing plating brighteners?
Electroplating additives and brighteners require continuous, non-pulsing ppm-level dosing to ensure uniform coating luster and prevent anode polarization. A JONSN surface treatment electroplating pump (MPG series with 40 μL/r displacement) delivers positive displacement flow with repeatability within ±0.2% and linearity within ±0.5%. Its all-PEEK and Zirconia ceramic wetted path resists chromic, sulfuric, and fluoboric acids, preventing metal ion leaching from spoiling delicate plating baths.
How does a JONSN hazardous chemical dosing pump handle non-Newtonian viscous polymers up to 80,000 MPa·s?
High-viscosity polymers cause stick-slip and motor stalling in standard pumps. The JONSN hazardous chemical dosing pump (DP/DX series 0.2–800 cc/rev) utilizes positive displacement large-torque heat-treated PEEK gear sets with optional steam or electric heating jackets. Maintaining media temperatures above the melting point, it delivers smooth, pulsation-free dosing for thick epoxy resins and polyurethanes up to 80,000 MPa·s with flow attenuation <2% over 10,000 hours.
