Hypro Pumps - Series 9303-SP

Series 9303 Cast Iron & Stainless Steel Self-Priming Pumps

Hypro self-priming centrifugal pumps handle big, high-capacity spraying jobs and tank filling with ease. They offer outstanding performance without the need for a flooded suction inlet. The pumps are ideal for sprayers that require pump mounting above the carrier tank.

The broad, versatile line includes models with rugged housings of cast iron and stainless steel that stand up to strong chemical herbicides. Stainless steel pumps are ideal for use with Roundup® or other acid applications. Polypropylene pumps are lightweight and provide excellent resistance to corrosive chemicals.

The series includes models 9303C-HM1C-SP, 9303S-HM1C-SP, 9303C-HM2C-SP, 9303S-HM2C-SP, 9303C-HM3C-SP, 9303S-HM3C-SP, 9303C-HM4C-SP, 9303S-HM4C-SP, 9303C-HM5C-SP, and 9303S-HM5C-SP.
