Designed specifically for Industrial, Fuel, & Anhydrous Ammonia Plants, our Remote Emergency Shutdown system was developed to eliminate costly hard-wiring of manual emergency-shutdown switches. Any number of radio transmitter units can be installed within 1,000 ft of a receiver control unit. The receiver control unit is powered with 120vac and includes a weatherproof potted air solenoid (not approved for Class D locations), an internal 120vac relay to kill power to the motor circuit, a portable handheld transmitter for the operator to carry with him and a wall mountable mushroom button transmitter to mount up to 1000' away

 The system is designed to work in conjunction with existing or new plant safety equipment and is easily installed. The ASK system can also be ordered to work in conjunction with our Truck Remote Units if required. Transmitter devices are low-voltage intrinsically safe units suitable for use in Class 1, Div 2, Group "D" hazardous environments. Transmitter batteries will last three-four years and have a test feature and low battery alarm.  

Remote stop-switch is rugged non-sparking cast aluminum and is fully sealed against extreme weather and temperature conditions. Receiver units are designed to easily interface and trip electrical, pneumatic, nitrogen, or mechanical plant shut-off equipment. BASE can supply actuators for these systems as required. Systems are pretested and shipped with detailed installation guide and schematics. A four-year full replacement warranty and 24/7 lifetime product support is included.

Before the turn of the 20th century, a rotary pump was generally understood to be a "gear pump," consisting primarily of two meshing gears which trapped liquid between the gear teeth and the pump housing creating small sealing cavities that transported fluid as it rotated, forcing the liquid out the other side. But in 1899 R. M. Blackmer came up with a vane-type pump design that was an important departure from the old gear principle. In contrast to the flow rate from a gear pump that drops steadily as the gear teeth wear away, the loss from a vane-type pump is practically negligible. As the vanes wear away at the tips, they simply move further out of the rotor slots to self-adjust and maintain the original rate. That style pump is still the premier choice of the propane industry today.  And as a leader in first innovations Blackmer continues that trend with the 3021 pump. Blackmer's innovations include developing the first sliding vane pump, the first practical positive displacement liquefied gas pump, and more recently, the patented cavitation & noise suppression technology.

The LGL3021 was designed to provide the same foot-to-flange and flange-to-flange dimensions as a competitive replacement pump model. This allows for easy pump installation during change overs or plant maintenance without changing piping or motor drives because the inlet and discharge flanges are on the pump shaft centerline. A major benefit is the LGL3021 has the same horsepower requirement as the competitive pump but provides 13% to 25% more flow, depending upon the LPG installation and application conditions.

I recently visited and toured the impressive Blackmer manufacturing plant in Grand Rapids and found they are a vertically integrated company; in that they own and operate their own captive castings foundry. This allows them to control the quality of the iron and steel used in the manufacturing of Blackmer pumps while operating more efficiently.
