Description

The Cat Pumps Model 1050 is a powerhouse in the 15PFR (Plunger, Flush, Reciprocating) series. This is a solid-shaft, triplex plunger pump designed for continuous-duty industrial applications. Unlike the smaller high-speed pumps, the 1050 is engineered to run at a lower RPM, which significantly extends the life of the seals and internal drive components.

Technical Specifications

• Flow Rate: $10.0\ \text{GPM}$ (Gallons Per Minute).

• Pressure Range: $100$ to $2200\ \text{PSI}$.

• Max Speed: $958\ \text{RPM}$.

• Shaft Diameter: $30\text{mm}$ (Solid, double-ended).

• Inlet Port: $3/4″\ \text{NPT(F)}$.

• Discharge Port: $1/2″\ \text{NPT(F)}$.

• Crankcase Capacity: $42\ \text{oz}$.

Key Features

• Triplex Design: The three-plunger configuration provides a smooth, nearly pulse-free liquid flow.

• Lower RPM: Running at $958\ \text{RPM}$ (compared to $3450\ \text{RPM}$ on direct-drive pumps) reduces friction, heat, and mechanical wear, making it suitable for $24/7$ operations.

• 316 Stainless Steel Valves: The valve seats and springs are built for maximum durability and chemical resistance.

• Solid Ceramic Plungers: Provides a smooth, hard surface that resists scoring and extends the intervals between seal replacements.

Primary Applications

• Industrial Washdown: Large-scale food processing or manufacturing plants.

• Central Cleaning Systems: Where one pump feeds multiple spray stations.

• Misting/Odor Control: Large-scale outdoor cooling or waste management facilities.

• Agricultural Spraying: High-volume livestock or crop maintenance.

Maintenance & Service Kits

To maintain the $2200\ \text{PSI}$ rating and prevent downtime, use the following specialized kits:

• Seal Kit (Part #30025): Includes high-pressure and low-pressure seals for all three cylinders.

• Valve Kit (Part #30023): Includes valves, seats, springs, and O-rings (two kits required for a full overhaul).

• Plunger Kit (Part #43501): Includes the $24\text{mm}$ ceramic plungers if they become cracked or scored.

System Requirement: Because this pump moves $10\ \text{GPM}$, the inlet plumbing is critical. You should use a minimum $1″\ \text{ID}$ reinforced suction hose. If the pump “starves” for water, you will experience cavitation, which will lead to a loud knocking sound and rapid destruction of the manifold and seals.
