DH 100 Cast Iron Drainage Pump 300lmin 4.4m for Emptying Sumps
EXTREME PUMPING POWER: Moves a massive 300 L/min (18 m³/h) with an 18.5-meter max lift head, providing lightning-fast drainage for large basements, construction sites, and pits.
MANUAL OPERATION DESIGN: Built without a float switch for applications requiring continuous, user-controlled pumping to drain water down to the absolute lowest levels.
HEAVY-DUTY BRASS IMPELLER: The open brass impeller easily tackles dirty water and passes suspended solids up to 10 mm, preventing clogs and reducing maintenance.
RUST-RESISTANT BUILD: Crafted with a cataphoresis-coated cast iron body and a durable stainless steel motor cover, offering exceptional protection against corrosion.
PROFESSIONAL MOTOR SEALING: Features an advanced double mechanical seal with an oil barrier (IPX8 waterproof) to ensure the motor stays dry even during deep submersion.
Product information
The Pentax DH 100 is a professional-grade, high-head Italian submersible drainage pump engineered for heavy-duty domestic, civil, and agricultural applications. Built with a solid cataphoresis-painted cast iron body and a corrosion-resistant stainless steel motor shell, it provides extreme durability and rust protection for long-term submersion down to 5 meters.
Unlike lightweight plastic pumps, the DH 100 features a heavy-duty open brass impeller designed to handle drainage water with suspended solids up to 10 mm in diameter. It generates extreme discharge pressure (up to 18.5 meters of head) while maintaining a massive flow rate of up to 300 L/min, allowing you to clear huge volumes of water quickly.
Designed for reliable continuous manual operation, the DH 100 includes a built-in capacitor, internal thermal overload protection, and a professional double mechanical seal with an oil barrier (silicon carbide on the pump side). Equipped with a 10-meter heavy-duty H07 RN8F cable, it is the ultimate reliable choice for demanding drainage tasks where full user control is required.
Note: Suitable for clean or dirty drainage water with suspended solids up to Ø max 10 mm at liquid temperatures from 0°C to +40°C.
