Blackmer Pumps and Blackmer Compressors
Blackmer was incorporated in 1903 and is the leading manufacturer of positive displacement pumps, centrifugal pumps and compressors for the transfer of liquid and gas products. Blackmer products are used in a variety of industries including LPG, Chemical Processing, Refined Fuels, Petroleum, Food & Sanitary and the Mobile Transport industries.
Blackmer Sliding Vane Pumps
These pumps have a number of vanes that are free to slide into or out of slots in the pump rotor. When the pump driver turns the rotor, centrifugal force, rods, and/or pressurized fluid causes the vanes to move outward in their slots and bear against the inner bore of the pump casing forming pumping chambers. As the rotor revolves, fluid flows into the area between the vanes (pumping chambers) when they pass the suction port. This fluid is transported around the pump casing until the discharge port is reached. At this point the fluid is squeezed out into the discharge piping.
EBlackmer ccdentric Movement Pumps
These pumps consist of a cylinder and a pumping element mounted on an eccentric shaft. As the eccentric shaft is rotated, the pumping element forms chambers within the cylinder, which increase in size at the intake port, drawing fluid into the pumping chamber. The fluid is transported to the discharge port where the pumping chamber size is decreased. This action squeezes the fluid out into the discharge piping.
Blackmer Centrifugal Pumps
The simplest type of centrifugal pump is the single stage machine that consists fundamentally of a rotating element, called an impeller, and a casing. Liquid is led to the eye or center of the impeller and is set into rotation by the impeller vanes. By virtue of centrifugal force the liquid is thrown from the rim or periphery of the impeller with a considerable velocity and pressure. The casing, which closely surrounds the impeller, has a volute shaped passage of increasing area, which collects the liquid leaving the impeller, and converts a portion of its velocity energy into additional pressure energy. This casing passage leads to the discharge nozzle of the pump where it is forced into the discharge piping.
Blackmer Peristaltic Hose Pumps
The principle of the peristaltic hose pump is based on the alternating contraction and relaxation of the hose forcing the contents through the pump and into the discharge piping. A smooth wall, flexible hose is fitted in the pump casing and is completely squeezed between two shoes on the rotor and the inside of the pump casing. The rotating action moves the product through the hose at a constant rate of displacement without slip. The hose restitution after the squeeze produces an almost full vacuum that draws the product into the hose from the intake piping. The pump casing is half-filled with lubricant to cool the pump and lengthen the service life of the shoes and hose. Since the product only contacts the hose and not the internal pump components, this pumping technology is very suitable for abrasive and corrosive applications.
Blackmer Reciprocating Gas Compressors
The reciprocating compressors create a low-pressure area in the compression chamber when the piston moves from the highest point of the stroke to the lowest point. Gaseous product (at a higher pressure) moves into the compression chamber. This volume of gas is then displaced when the piston moves to the top of the stroke. Equipped with high efficiency valves, ductile iron cylinders, self-adjusting piston rod seals and other robust features, these compressors are designed to provide maximum performance and reliability under the most severe service conditions.
Blackmer Rotary Vane Compressors
This compressor incorporates simple, dependable, rotating sliding-vane technology to provide sustained performance pressures or vacuums for off-loading liquids. A rotary vane compressor takes in atmospheric air through a high performance inlet air filter, and discharges the compressed air at a higher pressure into a cargo tank. The elevated pressure pushes the liquid out through the discharge piping.
Blackmer Screw Compressors
Within the compressor body there are two screws with matting profile: a female and a male screw, female having concave inlets and the male with convex helical inlets. The screws rotate in opposite directions with the female screw receiving the driving power and transmitting this power to the male screw through a set of synchronization gears.
As the screws rotate, the air is drawn into the inlet port and fills up the space between the screws. This phase is the Admission. The key phase is the Compression. It starts when the end of a male thread blocks the end of a female thread. The volume available between the compressor body and these two threads then progressively decreased during rotation. When this volume merges into the delivery outlet of the compressor, the third phase takes place, hence the Exhaust.
Throughout this process, there is no contact between the screws. This means no wear, total reliability, and non-pulsating air delivery. These compressor/blowers can be used in either a Mobil or stationary application and can be driven by a PTO, electric motor, or hydraulic power system. A complete range of dedicated ancillary product is available to support this product line.
