KLVP6 Gas-Liquid Mixed-Transfer Diaphragm Vacuum Pump
The Kamoer KLVP6 is a brushless diaphragm vacuum pump designed for gas transfer and intermittent gas-liquid mixed transfer in OEM equipment. Multiple single-head and dual-head configurations provide a choice between higher vacuum and higher flow.
Selected configurations can handle gas-liquid mixtures containing up to 60% liquid by volume, making the KLVP6 suitable for applications where occasional liquid may enter the pneumatic circuit. It is not intended for prolonged pumping of pure liquid.

Reference performance was measured using air at 25°C, standard atmospheric pressure, and no load pressure. Actual performance depends on gas composition, liquid content, temperature, tubing, filters, system resistance, voltage, and duty cycle.
For gas-liquid mixed transfer, the liquid content should not exceed 60% by volume, and prolonged pumping of pure liquid should be avoided. Mineral oil, strongly corrosive media, and contaminated fluids are not recommended. Chemical compatibility and performance should be verified under actual operating conditions.
