Depending on your reactor size and agitation requirements, DDPS offers Series 60 Drives or Lenze Drives that are designed to meet the special needs of glass-lined process vessel users.
Series 60 Drives
Series 60 Advantages
The Series 60 helical gear agitator drive was designed to meet the special needs of glass-lined process vessel users. Advantages of the Series 60 drive include:
- Long-life, low-maintenance design
- Large diameter, preloaded tapered roller bearings provide optimum blend of rigid shaft support for very low runout with low-profile design.
- Long L10 bearing life: 100,000 to 500,000 hours for output shaft bearings.
- Quality 10 helical gearing: no low- efficiency worm gear to heat up or belts to slip.
- Minimum numbers of parts, simplified construction and rugged, rigid ductile iron housing. Extremely low noise level.
- High drive efficiency gives lower power consumption
- Compact design reduces headroom requirements, simplifies vessel piping
- Infrequent oil changes: once a year is average
- Drywell construction eliminates oil leakage at output and input shafts
- Submerged oil lubrication means no oil pump or slinger to fail, no grease required – allows angular offset mounting
Series 60 Features
Series 60 is optimized for use over the entire working temperature range of a glass-lined reactor with a “non-metallic” shaft seal. There are two optional mounts – an angular-offset drive exceptional top-to-bottom turnover without costly baffling; or vertical-mounted drive for dependability and performance. The DDPS Series 60 drive can be retrofitted to any major brand reactor.Series 60 Specifications
- Fits on GL series reactors size 300 gallons and larger
Options
- Explosion-proof and multiple-speed motors
- Choice of dry-running single mechanical seals or lubricated double mechanical seals

Lenze Drives
Lenze Drive Advantages

- Compact design with fewer parts for easy installation and maintenance
- Check, add or change oil without removing the safety guard
- Largest output bearings in the size range provide unmatched L10 life (> 100,000 hours)
- Unique output shaft connection reduces shaft deflection to extend seal life
- Longer shaft lengths accommodate a wider range of tank configurations
- Leakproof reducer design
Lenze Drive Features
Lenze drives are optimized for use over the entire working temperature range of a glass-lined reactor with a “non-metallic” shaft seal. The DDPS Lenze drive can be retrofitted to any major brand reactor.Lenze Drive Specifications
- Fits on CTJ series reactors sizes 5 to 1,000 gallons
- Available from 1 to 30 HP with speeds from 11 to 125 RPM
Options
- Explosion-proof and multiple-speed motors
- Choice of dry-running single mechanical seals or lubricated double mechanical seals
