HCP F-21P 1 HP 2" Submersible Trash Pump

Up to 97 GPM • Handles 7/8" Solids • Multiple Voltage Options

The HCP F-21P Submersible Trash Pump is a 1 HP electric pump designed for dirty water, effluent, and debris-laden dewatering. It is built for professional use in applications where clear-water or sump pumps would clog or fail.

With a 2-inch discharge and the ability to handle solids up to 7/8 inch (22 mm), the F-21P is suited for construction dewatering, wastewater handling, and industrial drainage. It delivers up to 96–97 GPM, making it effective for moving high volumes of water at low to moderate head.

The pump features cast iron hydraulic components and a 304 stainless steel motor frame for resistance to abrasion and corrosion. Available in single-phase and three-phase configurations, the F-21P adapts easily to a wide range of jobsite and facility power requirements.

• cUL & UL Listed

Applications

The HCP F-21P is a true submersible trash / effluent pump, not a clear-water or sump pump. It is specifically designed for applications where water contains suspended solids, debris, or wastewater that would damage or clog standard pumps.

• Construction site dewatering
• Excavations and foundation drainage
• Wastewater and effluent handling
• Flooded basements and service areas
• Industrial and commercial drainage

Is This the Right Pump for Your Application?

Choose the HCP F-21P if you need:

• A 2" submersible trash pump with high flow capacity
• Ability to handle solids up to 7/8 inch (22 mm)
• A 1 HP pump for general dewatering and effluent applications
• Single-phase or three-phase electrical flexibility
• Continuous submersible operation with built-in motor protection

Consider a different pump if you need:

• Clear-water pumping only
• Explosion-proof equipment
• Larger solids handling or higher horsepower

Performance & Hydraulic Capability

• Maximum Flow: ~96–97 GPM
• Flow at 12 ft Head: ~97 GPM
• Maximum Head: ~48–50 ft
• Discharge Size: 2" (50 mm)

As with all centrifugal pumps, flow decreases as discharge head increases. The performance curve reflects a stable operating range suitable for general dewatering rather than high-pressure pumping.

Solids Handling & Impeller Design

The HCP F-21P uses an open impeller design that allows debris and solids to pass through the pump with reduced risk of clogging.

• Maximum solid passage: 22 mm (7/8")
• Cast iron impeller for abrasion resistance
• Suitable for wastewater, effluent, and dirty water

Construction & Materials

• Motor Frame: SUS304 stainless steel
• Casing / Volute: FC200 cast iron
• Impeller: FC200 cast iron
• Shaft: SUS410 stainless steel
• Bearings: 6202ZZ (upper), 6303ZZ (lower)

Sealing, Cooling & Motor Protection

• Double mechanical seals
• Upper seal: Carbon / Ceramic
• Lower seal: Silicon Carbide / Silicon Carbide (SiC/SiC)
• Oil-filled seal chamber (VG32 oil, 160 cc)
• External motor cooling
• Ingress Protection: IP68
• Thermal protection on applicable single-phase models

Electrical Options Explained

The HCP F-21P is available in multiple electrical configurations, all with identical hydraulic performance:

Single-Phase

• 120V, 1Ø: 9.6 A, capacitor start
• 240V, 1Ø: 4.8 A, capacitor start

Three-Phase

• 240V, 3Ø: 3.3 A
• 575–600V, 3Ø: 1.3 A

Voltage selection depends on available power and electrical requirements at the installation site.

Frequently Asked Questions

Can this pump run dry?

No. The HCP F-21P is designed to operate while fully submerged. Running the pump dry can damage the mechanical seals and reduce service life.

What do manual and automatic mean?

Manual pumps run continuously when powered on. Automatic operation uses a float switch to start and stop the pump based on water level.

How do I choose the right size pump?

Pump selection depends on required flow rate, total head, discharge size, and solid size. The F-21P is ideal for 2" discharge applications handling solids up to 7/8 inch.

Can the motor be submerged in water?

Yes. The pump is designed for continuous submersible operation and features an IP68-rated motor with double mechanical seals.

What size solids can this pump handle?

The HCP F-21P handles solids up to 22 mm (7/8").

What is the difference between a submersible trash pump and a sump pump?

A submersible trash pump is designed to handle water with solids and debris, while a sump pump is intended for relatively clean water. Trash pumps use open or vortex impellers and heavy-duty materials to reduce clogging in demanding applications.

Can submersible trash pumps run continuously?

Yes. Submersible trash pumps, including the HCP F-21P, are designed for continuous operation when fully submerged and used within their rated limits. Proper cooling, seal protection, and correct application are essential for long service life.
