CH&E Generac Magnum MCP5552 Diaphragm Trash Pump: Product Overview

The CH&E Generac Magnum MCP5552 is a diaphragm prime trash pump designed to move water in conditions where standard centrifugal pumps fail. Unlike centrifugal pumps, the MCP5552 diaphragm design has no impeller shaft or mechanical seal that can be damaged by sand, silt, or abrasive particles. This makes it a particularly effective choice for muddy water, sandy conditions, sediment-filled ponds, and any application where debris or solids content in the water would wear or clog a conventional pump.

The MCP5552 is self-priming and will continue to run dry after all water has been removed from the source, then automatically resume pumping when water pools up again. This automatic dry-run and re-prime capability makes it ideal for seepage dewatering, foundation drainage, and any intermittent fluid transfer task where operator supervision is limited.

The CH&E Generac Magnum diaphragm pump series is available in 2 inch (50.8mm) and 3 inch (76.2mm) port sizes, in gas, electric, and diesel engine configurations. Skid mount (S) and wheel mount (W) options are available to suit your job site setup requirements.

Why Choose a Diaphragm Pump Over a Centrifugal Trash Pump?

Understanding the difference between diaphragm prime pumps and wet-prime centrifugal trash pumps helps you select the right equipment for your specific job conditions.

CH&E Generac Magnum MCP5552 Diaphragm Trash Pump: Key Features

• No Impeller Shaft or Seal: Eliminates the primary failure point in centrifugal pumps when handling sand, silt, and abrasive particles
• Automatic Self-Priming: Diaphragm prime system clears air from the pump casing and suction line automatically, eliminating the need for manual priming before each use
• Runs Dry Indefinitely: Continues operating without damage after the water source is depleted, then automatically resumes pumping when fluid returns
• Handles Muddy and Sandy Water: Designed specifically for shallow and muddy applications including ponds, trenches, ditches, foundations, and seepage dewatering
• Multiple Port Size Options: Available in 2 inch (50.8mm) and 3 inch (76.2mm) configurations to match flow requirements
• Multiple Power Options: Available in gas, electric, and diesel engine models to suit job site power availability
• Skid Mount and Wheel Mount Options: Choose skid mount (S) for stationary applications or wheel mount (W) for portable, repositionable job site use
• Low Maintenance Design: Simple diaphragm mechanism reduces the number of wear components compared to centrifugal pump designs

Repair Parts for the CH&E Generac Magnum MCP5552 Diaphragm Trash Pump

Ken’s Distributing Company stocks genuine repair parts for the CH&E Generac Magnum MCP5552 diaphragm trash pump. The MCP5552 shares its core diaphragm pump platform with the broader CH&E 5500 Series aluminum diaphragm pump range, which means many components are sourced from the same proven parts inventory used across the MCP and CH&E product lines.

Common repair parts for the MCP5552 diaphragm trash pump include:

• Diaphragm: The primary wear component. Available in Neoprene, Buna-N, TPE, Rubber, and Viton materials to match your fluid type and operating conditions
• Flap Valve Assemblies: Require two per pump. Available in Neoprene, Buna-N, Neoprene with cloth insert, and Viton materials
• Diaphragm Rebuild Kit: Complete kit including diaphragm, flapper assemblies, and all necessary hardware for a full fluid-end rebuild
• Connecting Rod and Bearing: Drivetrain wear components serviced during major pump rebuilds
• Lip Seals and Gaskets: Case gaskets and oil seals replaced at each major rebuild to prevent fluid ingress into the drivetrain housing
• Bearings: Ball bearings and needle bearing serviced as part of full drivetrain rebuilds
• Strainer: Suction strainer inspected and replaced at each service interval to protect internal pump components
• Engine Adapter: Matched to your engine configuration: gas, electric, or hydraulic motor

To confirm exact part numbers for your MCP5552 unit, contact the Kendisco team with your serial number. Because engineering updates can occur during a production run, using the serial number ensures you receive the correct components for your specific pump build.

Diaphragm Material Selection for the MCP5552

Choosing the correct diaphragm material is one of the most important decisions when servicing the CH&E Generac Magnum MCP5552 diaphragm trash pump. The right material extends service life, reduces the frequency of repairs, and ensures the pump handles your specific fluid type reliably.

Maintenance Guidance for the CH&E Generac Magnum MCP5552 Diaphragm Trash Pump

The MCP5552 diaphragm trash pump is designed for low-maintenance operation, but regular inspection and timely replacement of wear components keep the pump performing reliably and extend its overall service life.

• Diaphragm inspection: Inspect every 250 operating hours. Replace at the first sign of cracking, stiffness, deformation, or reduced pump output. In abrasive or high-cycle applications, inspect more frequently
• Flap valve inspection: Check valve condition and seating at each diaphragm inspection. Replace valves showing wear, tearing, or failure to seat correctly
• Suction strainer: Inspect and clean before each use. Replace if cracked, blocked, or structurally compromised
• Connecting rod bearing: Grease through the grease fitting at regular intervals to prevent dry bearing wear
• Case gasket and lip seals: Replace at each major rebuild to prevent fluid ingress into the drivetrain
• Engine service: Follow the engine manufacturer’s oil change and maintenance schedule for your specific engine model and configuration

How Often Should I Rebuild the MCP5552 Diaphragm Pump?

Under normal operating conditions, plan for a full fluid-end rebuild every 500 to 750 operating hours, or at the first sign of reduced output, loss of prime capability, or visible diaphragm wear. Because the MCP5552 is designed to run dry and re-prime automatically, reduced self-priming performance is often the first indicator that the diaphragm or flap valves need attention.

Common Service Questions for the CH&E Generac Magnum MCP5552 Diaphragm Trash Pump

Can the MCP5552 handle sandy and silty water without damage?

Yes. The MCP5552 diaphragm design does not use an impeller shaft or mechanical seal, which are the components most vulnerable to sand and silt damage in centrifugal pumps. The diaphragm mechanism handles sandy, silty, and muddy water without the accelerated wear that would occur in a centrifugal pump operating under the same conditions.

What happens if the MCP5552 runs out of water?

The MCP5552 is designed to run dry indefinitely without sustaining internal damage. When the water source is depleted, the pump continues operating without harm. When water pools up again at the suction inlet, the pump automatically re-primes and resumes normal operation. This is a key advantage for seepage dewatering and foundation drainage applications where flow is intermittent.

What is the difference between the MCP5552 and the MCP5537 or MCP5538?

The MCP5537, MCP5538, and MCP5552 are all part of the CH&E Generac Magnum 5500 Series aluminum diaphragm pump platform. Differences between these models relate to port size, engine configuration, mount type, and specific performance specifications. Contact the Kendisco team at 303-699-7845 to confirm the exact differences between models and identify the correct repair parts for your specific pump based on its serial number.

Are MCP5552 repair parts the same as CH&E 5500 Series parts?

The MCP5552 is built on the CH&E 5500 Series aluminum diaphragm pump platform and shares many components with the broader 5500 Series parts inventory. However, specific part numbers can vary by engine configuration, model variant, and production date. Always confirm part numbers using your MCP5552 serial number before ordering to ensure you receive the correct components for your unit.
