HCP 50SFU2.8A Industrial Stainless Steel Submersible Effluent Pump – 1 HP, 120/240/575V, 96 GPM

Heavy-Duty Submersible Pump for Chemical Processing and Industrial Wastewater

Product Overview

The HCP Model 50SFU2.8A is an industrial stainless steel submersible effluent pump constructed from investment-cast SUS316/SCS14 stainless steel. It is used for managing corrosive fluids, seawater, and low pH liquids in mining, food processing, and chemical industries. The unit features a dry motor with Class B or F insulation and IP68 protection. This corrosion-resistant pump for low pH fluids fits demanding environments where standard materials fail. HCP is Taiwan's most successful submersible pump manufacturer.

Key Benefits of this Industrial Stainless Steel Submersible Effluent Pump

• Achieves efficient drainage with a maximum flow rate of 96 GPM (at 10' head).
• Resists corrosion from acidic and basic liquids (pH 4–10) using SUS316 stainless steel construction.
• Protects against chemical degradation with chemically treated Viton O-rings.
• Passes spherical solids up to 35mm using a vortex (U-type) impeller to reduce clogging.
• Prevents motor burnout with an integrated auto-cut thermal protector (single-phase models).
• Adapts to various power supplies with available single-phase and three-phase voltage options.
• Ensures reliable operation in seawater and abrasive environments typically found in mining and quarry wastewater.

Key Features of HCP 50SFU2.8A Submersible Effluent Pump

Investment-Cast SUS316 Stainless Steel

The pump casing, motor frame, and impeller use precision-cast stainless steel (SCS14/SUS316), offering superior durability against corrosion compared to standard cast iron or plastic pumps.

Viton O-Ring Seals

Chemically treated Viton O-rings provide enhanced resistance to acidic fluids, alkalis, and oils, ensuring the internal components remain sealed even in aggressive chemical environments.

Vortex Impeller Design

The U-type vortex impeller creates a whirlpool effect that allows long fibrous materials and solids up to 35mm to pass through without contacting the impeller, significantly reducing clogging risks.

Double Mechanical Seals

An abrasion-resistant double mechanical seal system (Carbon/Ceramic upper, Silicon/Carbide lower) in an oil chamber ensures long-term sealing integrity in dirty water or wastewater applications.

Epoxy Resin Cable Base

The cable entry features an epoxy resin seal that prevents moisture from wicking into the motor through the core wires, a common cause of submersible pump failure.

Auto-Cut Motor Protection

Single-phase stainless steel effluent pump models include an auto-cut protector that automatically shuts down the motor during overheating or over-current events to prevent permanent damage.

Performance Overview

The HCP Model 50SFU2.8A submersible effluent pump delivers reliable high-head performance, suitable for industrial applications. It reaches a maximum head of 46 feet and maintains flow rates up to 96 GPM at lower heads. Designed for continuous duty when properly submerged and operated within its performance curve

Applications

• Industrial wastewater treatment in food processing
• Acidic liquid drainage in mining and quarry operations

• Medical and research laboratory wastewater removal

Common Use

• Chemical processing plants
• Mining dewatering
• Food production facilities
• Aquaculture systems

Installation & Use Notes

• Installation: Verify voltage requirements (120V, 240V, or 575V) before connection. The 120V model comes with a standard plug; other voltages may require hardwiring.
• Submersion: This unit is a submersible pump and should be operated while submerged to ensure proper cooling.
• Solids Handling: The pump passes solids up to 35mm; avoid introducing larger debris to prevent blockage.
• pH Limits: Safe for operation in fluids with a pH range of 2 to 10.
• Maintenance: Check oil and mechanical seals periodically if used in abrasive wastewater environments.

Accessories & Add-Ons

• Control Switch: Pair with a Piggyback Float Switch for automatic on/off operation (Single Phase models).
• Hose Kit: Compatible with 2-inch layflat discharge hose for temporary dewatering setups.
