CAT Pumps 5CPQ6221G1.0220 Plunger Pump
Product Description
The CAT Pumps 5CPQ6221G1.0220 is a highly durable, industrial-duty 5-Frame triplex Plunger Pump specifically configured for high-flow, medium-pressure applications, such as large-scale pressure washing, reverse osmosis injection, and municipal cleaning systems.
Engineered with a robust construction, this pump features a 316 Stainless Steel Manifold for superior resistance to corrosive liquids and a Gearbox (G1) configuration designed for direct mounting to gas engines with a 1-inch straight horizontal shaft. This design simplifies installation and ensures optimal power transfer.
The pump delivers an outstanding flow rate of 7.4 GPM at a maximum pressure of 1,500 PSI. Crucially, this specific model uses the .0220 suffix, which confirms the use of EPDM (Ethylene Propylene Diene Monomer) seals and O-rings, providing excellent resistance to specific chemicals like ketones, hot water, and steam, while being rated for liquid temperatures up to 160∘F. The "Q" designation indicates that this is a Quiet model, reducing sound levels by -6 dBa compared to non-"Q" models.
