A piston pump with an offset crank mechanism is a positive displacement pump that utilizes an eccentric or offset crank mechanism to convert rotary motion to reciprocating motion. This design variation is often used on certain types of piston pumps for specific applications. Here are some key points about piston pumps with offset crankshaft arrangements: 1. Offset crank mechanism: Offset crank mechanism consists of a crankshaft with an eccentric or offset section. As the crankshaft rotates, the eccentric portion pushes or pulls a connecting rod connected to the plunger. This action converts the rotational motion of the crankshaft into linear reciprocating motion of the plunger. 2. Reciprocating plunger: In a plunger pump with an offset crank arrangement, the plunger moves back and forth within a cylinder or barrel. When the plunger is retracted, a vacuum is created that draws fluid into the cylinder. When the plunger extends, it pressurizes the fluid, forcing it out through the pump discharge. 3. Positive Displacement Pumps: Piston pumps with an offset crank arrangement are classified as positive displacement pumps. They displace a fixed volume of fluid with each stroke of the plunger, regardless of pressure. This makes them suitable for applications requiring precise flow control or where constant flow is required. 4. High Pressure Applications: Piston pumps with offset crankshaft arrangements are often used in high pressure applications because of their ability to generate enormous pressure. The design allows for the efficient transfer of power from the drive source to the plunger, enabling high pressure within the pump system. 90R130-DC-1-DE-80-S-3-C8-H-G1-GBA-30-35-30 90R130DC1DE80S3C8HG1GBA303530 90-R-130-DC-1-DE-80-S-3-C8-H-G1-GBA-30-35-30 90R130DC1DE80S3C8HG1GBA303530 90R130-DD-1-BC-80-P-4-F1-H-G8-GBA-35-35-24 90R130DD1BC80P4F1HG8GBA353524 90-R-130-DD-1-BC-80-P-4-F1-H-G8-GBA-35-35-24 90R130DD1BC80P4F1HG8GBA353524 90R130-DD-2-NN-80-R-7-F1-F-GB-GBA-30-30-28 90R130DD2NN80R7F1FGBGBA303028 90-R-130-DD-2-NN-80-R-7-F1-F-GB-GBA-30-30-28 90R130DD2NN80R7F1FGBGBA303028 90R130-DD-5-AB-80-P-4-C8-F-GB-GBA-42-42-24 90R130DD5AB80P4C8FGBGBA424224 90-R-130-DD-5-AB-80-P-4-C8-F-GB-GBA-42-42-24 90R130DD5AB80P4C8FGBGBA424224 90R130-DD-5-AB-80-S-4-C8-F-GB-GBA-42-42-24 90R130DD5AB80S4C8FGBGBA424224 90-R-130-DD-5-AB-80-S-4-C8-F-GB-GBA-42-42-24 90R130DD5AB80S4C8FGBGBA424224 90R130-DD-5-AB-80-S-4-C8-F-GF-GBA-17-17-20 90R130DD5AB80S4C8FGFGBA171720 90-R-130-DD-5-AB-80-S-4-C8-F-GF-GBA-17-17-20 90R130DD5AB80S4C8FGFGBA171720 90R130-DD-5-AB-80-S-4-F1-H-G8-GBA-42-42-24 90R130DD5AB80S4F1HG8GBA424224 90-R-130-DD-5-AB-80-S-4-F1-H-G8-GBA-42-42-24 90R130DD5AB80S4F1HG8GBA424224 90R130-DD-5-BB-80-S-3-F1-H-GB-GBA-35-35-22 90R130DD5BB80S3F1HGBGBA353522 90-R-130-DD-5-BB-80-S-3-F1-H-GB-GBA-35-35-22 90R130DD5BB80S3F1HGBGBA353522 90R130-DD-5-BC-80-L-4-C8-H-GB-GBA-42-42-28 90R130DD5BC80L4C8HGBGBA424228 90-R-130-DD-5-BC-80-L-4-C8-H-GB-GBA-42-42-28 90R130DD5BC80L4C8HGBGBA424228 90R130-DD-5-BC-80-S-3-F1-H-GB-GBA-35-35-28 90R130DD5BC80S3F1HGBGBA353528 90-R-130-DD-5-BC-80-S-3-F1-H-GB-GBA-35-35-28 90R130DD5BC80S3F1HGBGBA353528 5.
