Often these efforts are frustrated because of inadequate information on baselines, current situations, and future projections. National and international investors are longing for such information. Realizing the scarcity of accurate information and limitations of the present business community to provide it, Promark Services (Pvt) Ltd [PROMARK] was formed

Positive displacement pumps, unlike centrifugal or roto-dynamic pumps, will in theory produce the same flow at a given speed (RPM) no matter what the discharge pressure. Thus, positive displacement pumps are "constant flow machines". However due to a slight increase in internal leakage as the...

A particulate air filter is a device composed of fibrous materials which removes solid particulates such as dust, pollen, mold, and bacteria from the air. A chemical air filter consists of an absorbent or catalyst for the removal of airborne molecular contaminants such as volatile organic compounds...

A pneumatic filter is a device which removes contaminants from a compressed air stream. This can be done using a number of different techniques, from using a "media" type that traps particulates, but allows air to pass through to a venturi, to a membrane that only allows air to pass through.

A positive displacement pump can be further classified according to the mechanism used to move the fluid:
Rotary-type positive displacement: internal gear, screw, shuttle block, flexible vane or sliding vane, circumferential piston, helical twisted roots (e.g. the Wendelkolben pump) or liquid...

A pump is a device used to move fluids, such as liquids, gases or slurries.
A pump displaces a volume by physical or mechanical action. Pumps fall into three major groups: direct lift, displacement, and gravity pumps.[1] Their names describe the method for moving a fluid.
