Universal 1 Series - 420/520 High Capacity - Positive Displacement Pumps
Positive Displacement Pumps designed to overcome the challenge of accurate pumping at high-volume capacities.
FEATURES
Every revolution of the 420 pumps more than 1 gallons (6 liters) ; the 520, more than 2 gallons (8 liters). Ideally suited for tomato, vegetable and pet food industries and for chemical/industrial applications. FEATURES AND BENEFITS Sanitation Features
- Rotor/shaft connection sealed from product zone
- Sideway mounting capability for better draining
- 316L pump body and cover
- Non-galling Waukesha 鈥88鈥 alloy rotors standard; permits running at tighter clearances and higher efficiencies; 316 stainless also available
- Mechanical seals standard
- Aseptic model option available
Long-life Features
- Large diameter 17-4 PH shafts for greater strength
- Heavy duty bearing frame
- Double tapered roller bearings contribute further to precise rotor movement andlonger seal life
- Body bolted to gear case to maintain seal face contact, when removing cover androtors
- Greased lubed bearings for positive lubrication to all bearings over entire speed,temperature and pressure range
- No bearing in product zone
- Rotor nuts designed for extended service without loosening
