Materials of Construction Cast Iron Ductile Iron
Design Features Double pumps operate like Spur Gear Single Pumps, but offer two independent pumping units operated from a single power source to reduce equipment costs.  These may be used to pump from one fluid source to two applications, two fluids to two applications, or for proportioning two fluids together.  Standard pumps do allow some mixing within the pump, but optional seals are available to prevent mixing if needed. These pumps are standard with two inlet ports and two discharge ports, but may be configured with common inlet for metering flow to two applications or common discharge for metering two liquids together from separate sources. The Double Spur Gear Pump Series includes the following models: SG - Cast Iron Lip Seal Pumps SGN - Ductile Iron Lip Seal Pumps
