What are Sprayer or Pump Output and How are They Measured?

Pumps and sprayers commonly have a unit of measure specification – referred to as “output” , which is commonly measured in mcl, ml, or cc. Output determine how much fluid is dispensed each time the pump or sprayer is actuated.

 

MCL, or microliters, is a liquid unit of measurement that is equivalent to 1/1,000 ml, which is pretty small. It is commonly used to indicate fine mist sprayers and regular mist sprayers output.

 

Say you have a fine mist sprayer that has an output of 180 mcl; this would mean that for each spray action, you will get 180 microliters of liquid each time you actuate the sprayer.

 

Lotion pumps and some trigger sprayers, on the other hand, have a larger output capacity so the output measurement is measured in cc or ml. For most, lotion pumps have an output range of 0.5cc-4cc. Some high output pumps have output range of 4cc – 8cc.

 

When choosing the correct sprayer, it is important to understand your product so that you can properly determine the sprayer output for maximum results.

How Do Trigger Sprayer Bottles Pump Fluid?

Trigger sprayer bottles are an extremely useful type of machine and an excellent demonstration of basic plumbing principles. A spray-bottle head is made up of only a few parts. It has a trigger lever, which activates a small pump. This pump is attached to a plastic tube that draws cleaning fluid from the bottom of the reservoir. The pump forces this liquid down a narrow barrel and out a small hole at the gun’s muzzle. The hole, or nozzle, serves to focus the flowing liquid so that it forms a concentrated stream.

 

The only complex element in this design is the fluid pump, and it’s about as simple as they come. The main moving element is a piston, housed inside a cylinder. Inside the cylinder, there is a small spring. To operate the pump, you pull the trigger back, pushing the piston into the cylinder. The moving piston compresses the spring, so when you release the trigger, the piston is pushed back out of the cylinder. These two strokes of the piston, into the cylinder and out again, constitute the entire pump cycle.

 

The downstroke, the piston pushing in, shrinks the area of the cylinder, forcing fluid out of the pump. The upstroke, the spring pushing the piston back out, expands the cylinder area, sucking fluid into the pump. In a spray bottle, you need to suck cleaning fluid in from the reservoir below and force it out through the barrel above. In order to get all of the fluid moving through the barrel, the pump must only force the fluid up — it cannot force the fluid back into the reservoir. In other words, the fluid must move through the pump in only one direction.

 

The device that makes this possible is called a one-way valve. A trigger sprayer bottle has two one-way valves in the pumping system: one between the pump and the reservoir and one between the pump and the nozzle. Typically, the valve between the pump and the reservoir consists of a tiny rubber ball that rests neatly inside a small seal. The sides of the seal are angled so that the ball won’t fall through. Depending on the design, either gravity or a small spring holds this ball against the seal so that the water passageway is blocked off when you are not pumping. When the piston moves out (when you release the trigger), the expanding area of the cylinder sucks on the fluid below, pulling the ball up out of the seal. Since the ball is lifted up, fluid is free to flow from the reservoir. But when you squeeze the trigger, the outward force of the moving fluid pushes the ball into the seal, blocking off the passageway to the reservoir. Consequently, the pressurized fluid is pushed only into the barrel.
