When looking for sprayers and home improvement supplies, you may notice that different tools have different kinds of pumps; these things can lead to major changes in functionality. Here we’ll break down the differences between two popular options, gear pumps and diaphragm pumps, to help you decide what sprayer is the perfect fit for your work.
Gear pumps
In a gear pump, liquid flows into the pump from an input tube; from there, gears rotating in opposite directions suck the fluid in and send it around the container. These gears are extremely close together and are very close to the edges of the container as well, making sure no liquid can get stuck in this system or loop back around. This creates a slight vacuum where the liquid is being pushed around the container, allowing it to continue forward when it hits the open space between gears and funnels through the output tube.
Gear pumps don’t require a lot of pressure to operate and are well equipped to deal with more viscous liquids if necessary, allowing for smooth, continuous and precise application.
SprayMate’s Shower MAX and Lil’ Squirt sprayers use gear pumps, featuring a handheld application gun and optional extension wand to carefully and thoroughly douse whatever you need to clean, water, or protect!

Diaphragm Pumps
In a diaphragm pump, there's a chamber with valves covering the input and output tubes; these valves will open to suck liquid in or send it out based on the positioning of the rubber membrane. The membrane will move outward from the chamber, creating suction that pulls the input valve open and draws fluid in; that valve closes once the membrane moves inward. Once that happens, the output valve is pushed out and the fluid is released from the chamber and sent out into the next part of the system.
The material used in diaphragm pumps makes them great for more harsh chemicals and solutions, avoiding corrosion; their output pressures and flow rates are changeable as well, making them even more useful. Sprayers with diaphragm pumps are extremely versatile for this reason, making them fitting for nearly any job!
SprayMate’s Tornado and Storm sprayers use diaphragm pumps, offering a carbon fiber wand and two different nozzles to apply to a wide range of uses and coverages. They’re great for fertilizing, disinfecting, and chemical application; a Tornado or Storm sprayer can be used for virtually any task.
