Lightweight triplex plunger pump

Abstract

The lightweight triplex plunger pump provides high pressure and flow output in a compact unit size. The lightweight triplex plunger pump can be used in a number of machines where there is a need for high pressure/high flow ultra-portable device. The lightweight triplex plunger pump of the present invention is mostly comprised of a crank casing having a crankshaft and a plunger assembly which are enclosed within the crank casing; as well as a pump head or a fluid chamber for handling the fluid. The pump head further includes a suction manifold connected with the fluid reservoir through an inlet; a discharge manifold that pumps out the pressurized fluid through outlet; and a pump chamber for compressing the pump using the reciprocating movement of the plunger. Both the suction manifold and the discharge manifold includes openings that open within the pump chamber and valve configured within said opening. The movement of the plunger causes valves to open or close to suck the fluid from the suction manifold into the pump chamber and pump out the pressurized fluid out of the pump chamber into the discharge manifold.

         6 . The lightweight triplex plunger pump of  claim 1 , wherein the discharge manifold includes an outlet to pump-out a pressurized fluid. 
     
     
         7 . The lightweight triplex plunger pump of  claim 1 , wherein the lightweight triplex plunger pump is made of a thermoset material such as epoxy, silicone, polyurethane or phenolic. 
     
     
         8 . The lightweight triplex plunger pump of  claim 1 , wherein the triplex plunger pump may provide an output at a minimum of 1 gpm at 1000 psi pressure. 
     
     
         9 . A method of working a lightweight triplex plunger pump which comprises of:
 providing a lightweight triplex plunger pump further comprising of:
 a crankshaft enclosed within a crankshaft chamber of a crank case, wherein a pulley end of the crankshaft extends out of the crank case and further connected with an electric motor which rotates the crankshaft; 
 a three sets of a plunger assemblies each configured within a separate plunger assembly chamber within the crank case and each set of the plunger assembly is connected with the crankshaft, wherein the rotation of the crankshaft causes reciprocating movement of the plunger assembly within their respective plunger assembly chamber; 
 a pump head connected with the crankcase which further includes a suction manifold having a plurality of suction chambers; a discharge manifold having a plurality of discharge chambers; and a pump chamber, wherein each suction chamber of the plurality of suction chambers and each discharge chamber of the plurality of discharge chamber includes an opening that opens within the pump chamber; 
 at least 1 (one) suction valve configured within the opening of each suction chamber of the plurality of suction chambers to open or close said openings; and 
 at least 1 (one) discharge valve configured within each opening of each discharge chamber of the plurality of discharge chambers to open or close said openings; 
   
       wherein the suction manifold is connected with a fluid reservoir using an inlet while the discharge manifold includes an outlet to discharge the fluid out of the pump; 
     
     
         10 . The method of working a lightweight triplex plunger pump of  claim 9  further includes steps of rotating the crankshaft using the electric motor that in turn moves the plunger in a forward and backward direction. 
     
     
         11 . The method of working of a lightweight triplex plunger pump of  claim 9 , wherein the backward direction movement of the plunger creates a vacuum within the pump head causing the suction pump to move and open the opening causing the fluid to suck in the pump chamber from the suction chamber while keeping discharge valve close. 
     
     
         12 . The method of working of a lightweight triplex plunger pump of  claim 9 , wherein the forward movement of the plunger compresses the fluid within the pump chamber that in turn opens the discharge valve causing a pressurized fluid to pump out within the discharge chamber and hence out of the lightweight triplex plunger pump through the outlet. 
     
     
         13 . The method of working a lightweight triplex plunger pump of  claim 9 , wherein the triplex plunger pump may provide a pressurized fluid output of at least 1 GPM at 1000 PSI.
