A swash plate type piston pump includes a plurality of pistons, a cylinder block including a plurality of cylinders for housing the pistons, a swash plate for reciprocating the pistons to expand and contract volume chambers of the cylinders with the rotation of the cylinder block, a biasing mechanism for biasing the swash plate in a direction to increase a tilting angle, a first control pin for driving the swash plate in a direction to reduce the tilting angle according to a first load pressure, and a second control pin for driving the swash plate in a direction to reduce the tilting angle according to a second load pressure. The first and second control pins are connected in series.

The present invention provides an improved pump assembly incorporating a liquid pump and an air pump and which pump includes a flexible annular diaphragm member coaxially about a piston-forming element forming a component with the liquid pump.

Provided is an intensifier capable of cleaning a portion where pressurized raw material adheres without disassembling the inside. The intensifier for pressurizing raw material using medium supplied from a driving pump including: a low-pressure cylinder to which the medium is supplied; a high-pressure cylinder fixed to the low-pressure cylinder; a piston that slides inside the low-pressure cylinder and the high-pressure cylinder by the medium supplied to the low-pressure cylinder; a bottom adapter that pivotally supports the piston; and a resin portion disposed on an inner periphery of the bottom adapter.

A well operation facility including a first pump for delivering mud and cement to a borehole, a second pump for delivering mud to the borehole; a third pump for delivering the mud to the borehole, an inlet manifold coupled to each of the pumps for delivering the mud and/or cement to the pumps, and a discharge manifold coupled to each of the pumps for delivering the mud and/or cement at a pressure. In some embodiments, the first pump, the second pump, and the third pump are configured to be isolated from each other and to be used in series, parallel or as backups to each other.

A compressor assembly having a high velocity muffler system which produces a particle-free compressor pump feed while reducing noise output from the compressor assembly during compressing operations. The high velocity muffler system is maintenance-free and comprises an inertia filter. The compressor assembly uses a method for producing a compressor pump feed and reducing noise during compressing operations by processing a gas through the high velocity muffler system which has an inertia filter and a muffler chamber to produce a compressor pump feed which can be compressed by a pump assembly.

A high and low-pressure integrated air pump includes a single housing including an air inlet and an air outlet. A high-pressure pump is disposed within the housing and in fluid communication with the air inlet, and uses a first outlet passage to discharge to the air outlet. A low-pressure pump is also disposed within the housing and in fluid communication with the air inlet, and uses a second outlet passage to discharge to the air outlet.

The invention relates to a combination metering assembly for filling liquid products into containers. The invention is characterised by a base unit (1) and pump components (3, 4, 5, 6, 11, 12, 13, 14) of at least two different pump types for a metering operation, wherein the pump components of each pump type can be combined with the base unit in order to form a pump system of the corresponding pump type, and the base unit has connection means (19, 23) for this purpose which are compatible with the connections of the pump components. The combination metering assembly can be adapted to different metering situations with little complexity and has a comparably small space requirement.
