At Liquid Handling Equipment, Inc. in Charlotte, NC, we are pleased to offer pump equipment from the Roper Pump Company, which is recognized worldwide as a leading provider of innovative fluid handling solutions including external gear pumps & flow dividers and progressing cavity power sections & pumps. Roper was established in 1857, and they leverage unsurpassed fluid dynamics expertise to deliver engineered offerings in the most challenging applications. Call us to help you configure the right Roper pump for your needs.

The Roper 2AP12 Series A pump is adaptable to a wide range of applications, pumping clean fluids such as pressure lubrication, hydraulic service, fuel supply or general liquid transfer. The precise manufacturing tolerances provide minimum clearances for maximum pumping efficiency. Typical applications for the 2AP12 include Pressure Lubrication, Hydraulic Service, Fuel Supply and General Transfer. This pump has an internal pressure relief valve with a factory setting that is not the same as the pressure setting required in your application. The relief valve must be positioned as shown in instructions for direction of rotation otherwise the valve will be inoperable, and the discharge pressure will not be working against the relief valve. If the builtin relief valve is used, it is mandatory that the relief valve be set BY THE USER, since maximum relief valve pressure depends upon the viscosity and specific gravity of the liquid, the flow rate pump RPM, and also the initial relief valve setting. A builtin relief valve should not be used on applications where the discharge must be closed for more than a few minutes. Prolonged operation with the relief valve fully bypassing will cause heating of the liquid circulating thru the valve, thus resulting in possible damage. This pump has a packing ring type shaft seal. Operate the pump under normal conditions and, after a short runin period, examine the packing for leakage. If leakage is excessive, stop the pump and follow the procedure described below. A slight leakage is a necessary and normal condition for packing and allows for expansion and proper seating.

This is a general purpose Roper A series Pump for Pressure Lubrication, Hydraulic Service, Fuel Supply and General Transfer. The Roper A Series pumps are adaptable to a wide range of applications pumping clean fluids, such as pressure lubrication, hydraulic service, fuel supply or general liquid transfer. These pumps are designed to operate at standard motor speeds, with provisions for flange or foot mounting.

They are manufactured and assembled with close tolerances, and regularly tested to insure dependable performance. Accurate machining insures proper meshing, reduced friction and vibration, quiet, efficient operation, and long life. Factory assembled for clockwise rotation (facing the pump drive shaft end), most may be reassembled for operation with equal efficiency in a counter-clockwise rotation.

Large, hardened steel dowel pins insure positive alignment between the faceplate, case, and backplate. Four heavy duty sleeve bearings give positive support to pumping gears and insure long, efficient service. These internal bearings are lubricated by the fluid being pumped. The Bearings are special wear-resistant, high-lead bronze. (Iron and carbon bearings are available.) With only two moving parts, being the gears, the pumps run quietly.

These pumps operate smoothly and with equal efficiency in either direction of rotation. They effectively handle heavy, viscous materials such as asphalt, molasses, roofing compounds, and printing inks, as well as fuel oils, gasolines, and similar thin liquids. Pumps can be supplied in several materials of construction, with or without built-in relief valves. Pumps can be assembled either hi-drive or low-drive, and are available with conventional packed box or lapped-face mechanical shaft seal. They can be direct driven or driven through a built-in gear reduction with a wide range of ratios. These pumps operate equally well regardless of the mounting configuration or the direction of rotation.
