Anti-extrusion ring is used to provide firm support to the stripper rubber packer elements in a CTU stuffing box to prevent them from extruding too readily. It is a thin ring installed on the low pressure side of a seal to prevent elastomer extrusion into the clearance gap. It can also be used in conjunction with a vehicle solenoid valve has a plano-concave cross-section.

API centrifugal pumps are mainly designed for general refinery service. It consists of a set of rotating vanes, enclosed within a housing or casing, used to impart energy to a fluid through centrifugal force. It operates using kinetic energy to move fluid utilizing an impeller and a circular pump casing.

API compressor is a mechanical device that increases the pressure of a gas by reducing its volume. It increases the pressure on a fluid and can transport the fluid through a pipe. As gases are compressible, the compressor also reduces the volume of a gas. There are many different types of compressors that include reciprocating, rotary, centrifugal, and axial types.

Aramid packing is made of braids of aramid fiber, a strong organic substance, which are impregnated with PTFE dispersion and lubricant. This material is suitable for use as dynamic sealing in medias that contain solid particles. Its working temperature: -100 to 260oC.

Articulated Piston Compressor transfers rotational energy from a motor / pulley into a reciprocating motion used to compress air in a cylinder. The rotational motion is transferred through an eccentric and bearing assembly to the con-rod, on through the wrist pin to the piston itself. This is suited to tough industrial applications that require relatively high flow rates combined with pressure. These compressors are available in AC or pulley driven, with the smaller sizes also being available in DC.

Articulating Piston Pumps work by reduction of a volume using a sealed piston sliding within a cylinder. It has flow from 35 l/min to 365 l/min and pressures up to 175psi.

Clutch is a mechanism for transmitting rotation, which can be engaged and disengaged. There are many different vehicle clutch designs, but most are based on one or more friction discs, pressed tightly together or against a flywheel using springs. The spring pressure is released when the clutch pedal is depressed thus either pushing or pulling the diaphragm of the pressure plate, depending on type, and the friction plate is released and allowed to rotate freely.

Automatic degassing valves are intended to automatically vent gases and vapors that are commonly released from chemicals such as sodium hypochlorite or hydrogen peroxide or sulfuric acid. It is specially designed float material automatically vents built up gases on system start up and under working pressure. It can be used on feed side or discharge side of pump. The valve is designed to allow for the venting of gases and condensed vapor back to the feed tank, which improves priming on initial startups and continuous trouble free operation while working under pressure.

Automatic Pump Controller provides automatic stop/start on demand and incorporates a flow monitor to protect against dry run. The automatic pump controller eliminates the need for any manual switching of pumps installed for the purpose of pumping water from a reservoir to an overhead tank. It automatically switches on the pump when the water level in the tank falls below a certain low level, provided the water level in the reservoir is above a certain level.
