Key Features of HCP Model 50SA2.4A Stainless Steel Submersible Pump

SUS316/SCS14 Stainless Steel Construction

The entire pump, including the motor frame, casing, and impeller, is made from investment-cast stainless steel, providing superior resistance to corrosion from acidic fluids and seawater.

Dual Mechanical Seals

A dual mechanical seal system with silicon carbide faces ensures durability and prevents leaks, extending the pump's service life in abrasive and dirty water conditions.

Viton O-Rings

All O-rings are made from Viton, a high-performance fluoroelastomer that maintains its sealing integrity when exposed to chemicals, acids, and high temperatures, making this a reliable chemical-resistant sump pump.

Epoxy Resin Cable Base

An epoxy seal on the cable entry prevents moisture from wicking into the motor housing, protecting the motor from water damage and ensuring safe, reliable operation.

Auto-Cut Motor Protector

The single-phase motor includes a built-in thermal overload protector that automatically shuts the pump off if it overheats, preventing burnout during demanding use.

Performance Overview

The HCP Model 50SA2.4A is built for continuous duty cycles in demanding conditions. Its performance is characterized by a strong balance between flow and lift, operating effectively across its curve. This SUS316 wastewater pump is optimized for fluid temperatures between 0–40°C and a pH range of 2 to 10.

Applications

• Industrial wastewater treatment
• Corrosive water drainage for chemical and metal processing
• Seawater transport and drainage systems
• Wastewater management in food processing, dyeing, and brewing
• Pharmaceutical manufacturing fluid transfer
• Mining and quarry dewatering
• Aquaculture farm water circulation

Common Use

• Acidic liquid drainage
• Industrial seawater pump
• Low pH corrosive fluid transportation

Installation & Use Notes

• This is a submersible pump and must be fully submerged during operation to prevent overheating.
• Available in 120V single-phase and 240V three-phase configurations.
• The 120V model is a manual pump. For automatic operation, an external float switch is required.
• The bottom strainer prevents large solids from entering, but the pump is intended for liquids with limited solids.
• Ensure the power source matches the pump's voltage and phase specifications on the nameplate.

Accessories & Add-Ons

• For automatic operation, pair the 120V pump with a Piggyback Float Switch.
• Combine with a 2" layflat discharge hose for versatile dewatering setups.
