Unlikeconventional single diaphragm metering pumps, this linear flowreduces the need for pulsation dampeners and increases thereliability, performance, and safety of the metering pump system.Pump operation and plunger activation are accomplishedthrough a crankshaft.MT Series pumps offer either mechanical flow adjustment orflow adjustment through a variable-frequency drive (VFD).Pump pressure relief valve (54) is factory set to protect thepump from over pressurization. It is NOT to be used as a systempressure relief or regulator. Tampering with the relief valve willvoid manufacturer’s warranty.Maximum flow rate listed on page 3 of IOM should not beexceeded. API flow compliance is rated up to 8 GPH (30.28LPH). Running the pump at higher flow rates will not guaranteeAPI flow compliance and could result in pump damage. Consultfactory with questions regarding maximum flow rate.ID Plate Oil Fill Cap Pump AssemblyDrive EndPump AssemblyHydraulic End Pump AssemblyFluid EndRelief ValveDrainOutlet (both sides)Inlet (both sides)MT8 SpecificationPageOperation ................................................................................2Specifications ..........................................................................2Representative Drawings ........................................................5Safety Precautions ..................................................................6Installation ...............................................................................7Calibration ...............................................................................8Maintenance ............................................................................9Fluid End Parts List ...............................................................12Hydraulic End Parts List ........................................................14Drive End Parts List ..............................................................15Gearbox and Baseplate Parts List ........................................17Manual Adjust Gearbox Parts List ........................................18Troubleshooting .....................................................................19Replacement Parts Kits ....................................................... 20Manifold Pipe Plug Kits ........................................................ 20Warranty ................................................................................21
