The Graco 19X189 SoloTech ST30 Pump, MN/EP/PV/A1/A1/0 is a heavy-duty industrial peristaltic hose pump designed for transferring abrasive, corrosive, viscous, and shear-sensitive fluids. Its seal-less design helps reduce maintenance requirements while providing reliable fluid handling in demanding industrial environments.
Compatible Machines & Applications
This pump is a standalone industrial pump assembly and is commonly integrated into the following systems:
- Chemical dosing and injection systems
- Wastewater treatment equipment
- Mining slurry transfer systems
- Industrial fluid transfer skids
- OEM pumping systems
- Food and beverage processing equipment (material compatibility dependent)
- Pulp and paper processing systems
- Manufacturing and process fluid handling lines
- Chemical transfer and metering equipment
- Industrial batching and dispensing systems
Product Features
- ST30 platform with 30 mm hose size for industrial fluid transfer applications.
- MN configuration includes a medium-speed gearbox with NEMA motor mount.
- EP hose construction provides excellent chemical resistance.
- PV fluid connections offer durable corrosion resistance.
- Peristaltic pumping action minimizes product shear.
- Self-priming operation eliminates the need for additional priming equipment.
- Capable of dry running without damage to seals or valves.
- Reversible operation for flexible installation and fluid transfer requirements.
- No mechanical seals, valves, or packing glands in the fluid path.
- Suitable for abrasive, viscous, and shear-sensitive materials.

Frequently Asked Questions
The pump is designed for transferring abrasive, corrosive, viscous, and shear-sensitive fluids in industrial processing and fluid handling applications.
No. The 19X189 is a standalone industrial peristaltic pump assembly intended for integration into OEM systems and industrial process equipment rather than a specific sprayer model.
EP indicates an EPDM hose, which offers excellent resistance to many chemicals and industrial fluids.
Yes. The peristaltic design allows the pump to operate dry for short periods without the seal damage associated with conventional pump technologies.
