Suction-Pressure Laboratory Diaphragm Pump
The Suction-Pressure Laboratory Diaphragm Pump is widely used for the pumping and control of the discharge of thickened concentrates, pulps, and hydroclassifier sands in continuous laboratory test plants. This pump is also applicable to commercial installations where the volume of material to be handled is small. These Suction-Pressure Laboratory Diaphragm Pumps are available in ¾” simplex or 1¼” simplex or duplex units. Belt or motor drive can be furnished.
Laboratory Vertical Sand Pump
The Laboratory Vertical Sand Pump is particularly valuable in the continuous test plant. The feed falls directly onto the runner by gravity, requiring no intake head. This permits small volumes of heavy and coarse sands as well as frothy pulps to be pumped without excessive dilution. The wearing parts are of extra heavy material and quickly replaceable, while wear on the runner and follower is compensated for by an adjusting screw. The upper and lower bearings are enclosed in a single sealed bearing unit located above and away from the pulp and splash. Cone pulleys can be used to offer a choice of three speeds. This pump can be direct connected if desired.
Non-Lubricated Cylinder Laboratory Vacuum-Pressure Pump
The (Non-Lubricated Cylinder) Laboratory Vacuum-Pressure Pump is recommended for use in the chemical, food, brewing, distilling, and other industries. This unit is ideal for any application requiring a small compressor or vacuum pump with a clean oil-free discharge.
The cylinder and crankcase are contained in a single casting, and the compression cylinder is separated from the crankcase by a cast-in wall with a special seal which prevents oil from working along the crosshead.
The piston is of steel and incorporates a special three-piece carbon ring, with a metallic expansion ring between the carbon ring and the piston for self-lubrication which ensures trouble-free operation.
Piston Laboratory Vacuum-Pressure Pump
The (Piston Type) Laboratory Vacuum-Pressure Pump is recommended for laboratory use where more free air displacement and continuous operation at higher pressure and vacuum than shown elsewhere in this section are required. In addition to the operation of filters, pressure or vacuum may be required in connection with laboratory devices such as air lifts, agitators, and also in cleaning crushing equipment.
A pressure pump may be used in a laboratory for both pressure and vacuum and details are available upon request as to the most suitable way of making such an arrangement in your laboratory.
Rotary Laboratory Vacuum-Pressure Pump
The (Rotary Type) Laboratory Vacuum-Pressure Pump is a rugged unit of integral construction consisting of motor, pump, exhaust air cleaner, and circulating, visible, oiling system. The unit illustrated is recommended for use with the Laboratory Vacuum Filter. It may also be operated as a pressure pump if desired and will give the same excellent results. The (Rotary Type) Laboratory Vacuum-Pressure Pump can be furnished with vacuum and filtrate receiver, and gauge if desired. The same unit may be used for either small scale laboratory vacuum or pressure filtering.
Laboratory Water Pump
The gasoline – engine – driven Laboratory Water Pump is an inexpensive, self-contained unit for the low cost pumping of water. This pump is ideal for laboratories where a water supply is not readily available or low specific gravity solutions must be handled. The unit is comprised of a standard gasoline engine, V- belt drive, and pump all mounted on a single steel plate base for portability. The Laboratory Water Pump can be furnished without base and engine if desired. Price of individual pump or gas engine sent on request.
