FEATURES & BENEFITS
- Ball Bearings Standard
- Pumps are equipped with inner casing ball bearing installed outside of mechanical seal and a radial thrust ball bearing permitting heavy-duty service up to 250 PSI (17 BAR). Bearings are “Sealed for Life”.
- Integral Over-Pressure Relief Valve Standard
- Permits bypassing of liquid from discharge to suction side of pump. Prevents build up of pressure in discharge line. GG, HJ and HL size valve mounts on pump head. AS, AK and AL size valve mounts on pump casing.
- O-Ring Gaskets Standard
- O-Ring gaskets are used between casing and head plate and between casing and relief valve or valve plates. Flat valve gaskets furnished on GG, HJ and
HL size pumps. These gaskets provide a positive seal eliminating a chance for leak-age at these points.
- O-Ring gaskets are used between casing and head plate and between casing and relief valve or valve plates. Flat valve gaskets furnished on GG, HJ and
- Ductile Iron Parts Standard on AS, AK & AL Sizes
- Internal pumping gears (rotor and idler) are constructed of ductile iron for added strength in handling all types of liquids up to 15,000 SSU (3,300 cSt). HL size rotor also furnished in ductile iron.
