Description
Portable Chemical Resistant Wastewater Pump for Corrosive Environments and Seawater Applications
Product Overview
The HCP Model 50SA2.8A is a corrosion-resistant Stainless Steel Dewatering Pump configured for harsh industrial environments. It handles Corrosive Fluid Dewatering Pump tasks involving acidic wastewater, seawater, and chemical fluids with pH values between 2 and 10. The unit utilizes a SUS316 Stainless Steel Pump casing and Viton O-ring Submersible Pump seals to withstand aggressive media. This 1 HP Industrial Submersible Pump provides a durable solution where standard cast iron pumps corrode and fail.
As Taiwan's most successful submersible pump manufacturer, every HCP pump ensures reliable performance in demanding conditions.

Key Features of HCP Model 50SA2.8A
SUS316 Stainless Steel Construction
Precision-cast SUS316 stainless steel pump frames and casings provide superior resistance to rust and chemical corrosion compared to standard steel or plastic.
Viton O-Rings
Chemical-resistant fluoroelastomer seals protect internal components from acidic fluids and harsh chemicals found in industrial processing.
Vortex Impeller
The recessed impeller design creates a vortex flow to pass solids up to 3/8 inch without jamming, suitable for light slurry or solids-laden water.
Double Mechanical Seals
A carbon/ceramic upper seal and silicon carbide lower seal isolate the motor from the fluid, ensuring the seawater-resistant pump remains watertight.
Auto-Cut Thermal Protector
Single-phase motors feature an internal switch that automatically shuts down the pump during overheating or over-current events to prevent permanent damage.
Strainer Base
A robust stainless steel bottom strainer filters out large debris, stones, and pebbles that could damage the hydraulic mechanism.
Performance Overview
The HCP Model 50SA2.8A submersible pump delivers high-head performance relative to its size, reaching shut-off at nearly 51 feet. It maintains efficient flow rates even under moderate back pressure, providing approximately 40 GPM at 30 feet of head. The pump is rated for continuous duty when fully submerged in fluids ranging from 32°F to 104°F (0°C to 40°C), making it a reliable chemical resistant wastewater pump for industrial cycles.
Applications
- Chemical processing fluid transfer
- Metal processing factory drainage
- Acidic wastewater removal (pH 2–10)
- Seawater intake and discharge
- Food and wine industry wastewater
- Pharmaceutical plant drainage
- Emergency sump pump for corrosive environments
Common Use
Industrial dewatering, chemical spills, saltwater management.
Installation & Use Notes
- Verify the power source voltage matches the pump nameplate before connection.
- Ensure the pump is fully submerged to provide adequate motor cooling during continuous operation.
- Three-phase models require a control panel with appropriate overload protection; check rotation direction upon startup.
- Do not use in explosive environments or with flammable liquids.
- Regularly inspect the strainer base to ensure the intake remains clear of debris.
Accessories & Add-Ons
- Float Switch: Automate your system with an SJE PumpMaster Plus Float Switch for reliable on/off control.
- Discharge Hose: Connect with a 2-inch chemical-resistant layflat hose for temporary dewatering tasks.

Frequently Asked Questions
What is the best submersible pump for low pH fluids?
For fluids with pH levels between 2 and 10, the HCP Model 50SA2.8A is an excellent choice. Its SUS316 stainless steel construction and Viton O-rings are designed to withstand acidic conditions that would damage standard cast iron pumps.
Can the HCP 50SA2.8A be used for gold mining acid fluid?
Yes. The HCP 50SA2.8A is suitable for handling acidic wastewater commonly found in gold mining operations. Its corrosion-resistant materials provide reliable performance in aggressive mineral processing environments.
Is the HCP 50SA2.8A UL778 certified for safety?
Yes. The HCP 50SA2.8A carries UL778 and CSA c22.2 No. 108-14 certifications, confirming compliance with North American safety standards for submersible pumps.
What are the specifications of the HCP 50SA2.8A pump?
The pump features a 1 HP motor, 2-inch discharge, maximum flow rate of 90 GPM, maximum head of 50.9 feet, operating weight of approximately 35 pounds, and the ability to handle solids up to 3/8 inch.
Do I need a single-phase or three-phase dewatering pump?
This depends on your available power supply. The 50SA2.8A is offered in 120V and 240V single-phase configurations for standard power sources, as well as 240V and 575V three-phase options for industrial applications.
