Solvent pumping system
TLDR
In this paper, a liquid recirculation system for flammable solvents is described, where the liquid is pumped by an air-powered pump and an air turbine is mounted above the liquid level for driving the pump.Abstract:
This liquid recirculation system is particularly suitable for flammable solvents since the liquid is pumped by an air powered pump. The system has a solvent tank with a sink mounted on top of it for drainage into the tank. A centrifugal liquid pump is immersed below the liquid level in the tank for pumping liquid to a spout over the sink. A centrifugal air turbine is mounted above the liquid level for driving the pump. The liquid pump and air turbine have identical housings at opposite ends of a tubular housing. A drive shaft mounted in bushings or bearings at the ends of the tubular housing connects impellers in the turbine and pump. Each impeller is a flat disk with a plurality of flat upstanding blades with a substantially larger number of blades on the turbine impeller than on the pump impeller. Air enters the turbine tangentially and is discharged through an outlet on the top of the turbine. Liquid enters the pump through an opening on the bottom of the pump and is discharged through a tangential outlet extending in the same sense of rotation as the air inlet on the turbine.read more

Patent
Air driven pump
TL;DR: An air driven pump having a vane-type pump connected to a brush-type impeller is rotated by air striking the bristles of the brush at an angle tangential to the periphery thereof and thereby causing said vane to pump fluids without the use of electricity or other spark generating devices which could ignite flammable fluids.
