Product Details
Safe and reliable.
High vacuum, more flexible operation.
Dry corrosion protection, no coating required.
No wastewater, no pollution, no waste disposal costs.
Low operating cost.
Easy recovery: the cavity contains no liquid; the solvent is immediately recovered at the pump discharge port.
Low maintenance cost.
Indirect water cooling, precise temperature control.
Reliable integrated shaft sealing system.
Thermal protection switch, high-temperature protection.
Gas ballast/liquid flushing port, suitable for multiple processes. Stage pressure release valve (GDP250/GDP400), quickly establishes vacuum,
saves power consumption.
Vertical installation, convenient for liquid discharge.
Robust structure: can withstand disturbances during the process.
Short gas flow path.
No gas temperature drop at the stage: removes cold spots to prevent condensation.
Solid particles are blown out of the pump cavity: prevents solid buildup.
Short gas flow path
Red: compression process
Blue: inlet
Orange: outlet
Green: no compression passage (increased volume, condensation)
