Pump Characteristics
The 200LR (Liquid Ring) Self-Priming Pump handles products with entrained air as well as maintaining its prime when
other pumps become air bound. This feature makes the 200LR the best choice for complete emptying of tanks and lines
during normal process or cleaning-in-place (CIP).
In addition to being an excellent CIP return pump, the 200LR can run in either direction, making it possible to fill or
empty tanks with the same pump.
The 200LR Self-Priming Pump is built for extremely durable service. The casing, backplate and impeller/stub shaft are
316L stainless steel for extra strength and resistance to line shock and corrosion. Large bearings and shaft provide positive
alignment and minimize vibration.
The pump is available with two standard seal types:
•
Type 1- Single mechanical seal, external mounted and balanced.
•
Type 4 - Double mechanical seal with flush housing.
All seal components are interchangeable between models. All seal assemblies utilize an externally mounted balanced
rotary seal for longer seal life and better sealing capability. The stationary seal face is reversible and replaceable.
Performance Characteristics
Quality Control
Prior to shipment, each pump undergoes a performance
test for design flow rate and design pressure.
