Electrically Heater Gear Metering Pumps

Designed specifically for the precise metering and continuous transport of high-viscosity chemical media prone to solidification, this equipment is widely used in applications such as molecular distillation, reactor feeding, and precision coating. It features an all-stainless-steel pump head, with options for leak-free magnetic drives or explosion-proof configurations with dual mechanical seals. Driven by servo or variable-frequency motors, the system ensures stable metering with low shear and minimal pulsation.

Advantages

1. Integrated electric heating jacket with real-time thermocouple temperature monitoring ensures uniform temperature control and eliminates localized overheating. No steam or thermal oil piping is required, simplifying installation and wiring.
2. Low-shear gear design preserves molecular chains, making it ideal for feeding materials such as cardanol (cashew phenol) into molecular distillation systems.
3. High metering precision with flow rate linearly adjustable via rotational speed, suitable for continuous, quantitative feeding.
4. Material options include 304, 316L, and duplex stainless steel. Sealing options include single or double mechanical seals, as well as leak-free magnetic coupling.

Suitable Media

High-viscosity, easily solidified materials such as cardanol (cashew phenol), sulfur, hot-melt adhesives, paraffin wax, bitumen (asphalt), epoxy resins, polyols, isocyanates, and acrylic adhesives.

FAQ
1. Electric heating vs steam jacket?
Electric heating version is easy to install without steam piping, better for small flow precision dosing.

2. Suitable for cardanol molecular distillation?
Yes, it is the matched feed pump for cardanol distillation, stable viscosity and consistent feeding rate.

3. Zero leakage option?
Magnetic drive design is available for toxic and volatile media such as isocyanate
