Pumps consist of many parts in addition to the motor. These can include pump gaskets, pump safety seals, and pump heads, to name a few. The pump head is the part of the pump that actually propels the water. Types of pump heads include centrifugal pedestal pump heads, rotary gear pump heads, well pump heads, and more. Products vary by outlet size, inlet size, material of construction, temperature range, GPM, and more.
