GX and X Series

General Duty Pumps

Design

Blackmers GX and X series models are available in 2,

2.5, 3 and 4 inch flanged port sizes with capacities

from 30 to 520 U.S. gpm (114-1,855 lpm). Cast iron

construction is standard on all models. The X4 model

is also available in ductile iron construction. All models

have external ball bearings isolated from the pumpage

by mechanical seals.

The GX type pumps feature an integral head-mounted

gear reduction drive with oil lubricated, hardened

helical gears that provide quiet trouble-free operation.

Gear shafts are supported at both ends by ball

bearings for smooth operation and long life. A splined

shaft simplifies alignment of the pump and reducer,

and the reducer can be rotated on the pump head

to accommodate a variety of motor sizes without

shimming.

Application

Blackmers GX and X type pumps are designed to

handle a wide range of non-corrosive, non-abrasive

industrial liquids and petroleum products. Typical

applications include fuel oils, lube oils, jet fuels,

gasoline, edible oils and a variety of solvents and

thinners such as esters, ketones, naphthas, ethers,

amines, aromatics, alcohols, terpenes, glycols and

many other similar liquids.

Benefit

Blackmers positive displacement rotary pumps

utilizing their unique sliding vane design offers the

best combined characteristics of sustained high level

performance, energy efficiency, trouble-free operation

and low maintenance cost. Also, the high suction lift

capabilities of these pumps makes them especially

suitable for pumping from underground tanks, bulk

plant service and aircraft refueling.
