Shaft seal - Import export

ASCO CO2 Transfer Pumps have steel housings and long life shaft seals. The pumps have hardened steel gears and thrust washers to give long service life. The mechanical seal fitted provides leak free operation. These economical pumps need no lubrication and no daytoday maintenance. A unique design allows parts to adjust automatically for wear. Highest efficiency is maintained for a very long time. Installation is simple as no chain or belt drives or gear reduction motors are required. Pumps can be directly connected to standard speed lowcost electric motors. By simply changing the shaft rotation, pumps can be used to pump in or out through the same piping.
