See page 38 for list of equipment included with these pumps The RELIABLE Electric Vacuum Pumps areautomatic; noiseless; and draw condensation andair continuously when in operation. With theirdouble speed reduction, they work so perfectlythat they use but i to i the power required to op-erate other vacuum pumps. The cost for electriccurrent is lower in proportion. See next page for detailed description Forty-Two VACUUM HEATING EQUIPMENT DESCRIPTION OF RELIABLE RETURN LINE ELECTRIC VACUUM PUMPS Nos. 122,123,124 and 125 The RELIABLE Pumps are simple in design and dur-ably constructed, and can always be depended on tooperate satisfactorily, year in and year out. Following is a detailed description: Cylinders. These pumps have two vertical, single-actingcylinders, which always draw air and condensationsteadily when in operation. The cylinders are heavyiron. Large Capacity. The pumps have unusually large page 78 for number square feet radiation each pumpis capable of handling.
