n: flow that is variable;unstable flow.

n: 1. any gas or liquidcharged, chambered device that minimizes periodic increases and decreases in pressure (as from a mud pump). 2. a device used to reduce pressure pulsations in a flowing stream.

n: 1. a kinds of device that absorbs vibration, which removes instantaneous rhythmic wave propagation when reciprocal pump enforces to fluid. 2. for protecting the pressure gauge from continued vibration, fine screen plate fixed on the slim tube of contin

n: 1. a generator that produces repeating pulses or pulses initiated by signals. 2. a displacement meter accessory coupled to the measuring element and designed to produce a series of electrical pulses whose number is proportional to the volume measured and whose frequency is proportional to the flow rate. Also called pulser.

n: any of the various techniques by which the whole number of meter pulses are counted between two events (such as detector switch closures). Any remaining fraction of a pulse between the two events is calculated.

n: vesicular obsidian formed from gas-filled lava that cooled rapidly. It is often light enough to float on water.

n: a device that increases the pressure on a fluid or raises it to a higher level. Various types of pumps include the bottom- hole pump, centrifugal pump, hydraulic pump, jet pump, mud pump, reciprocating pump, rotary pump, sucker rod pump, and submersible pump.

n: the ratio of drilling pump valid power and rated power.

the output of the pump at stated conditions divided by the ideal output.

n: an arrangement of valves and piping that permits a wide choice in the routing of suction and discharge fluids among two or more pumps.

n: The arrangement of lines and valves used to direct and control fluid on a pumping unit. The manifold on the pump suction is generally known as the inlet or low-pressure manifold. The corresponding manifold located on the pump discharge is commonly known a

v: to pump (a well) so that the fluid level drops below the standing valve of the pump and the pump stops working.

pumping all the fluid out of the wellbore to the point where free gas enters the pump.
