CB100 Dual Counter-Posed Impeller Centrifugal Water Pump 80 L/min 40.8m
HIGH-EFFICIENCY COUNTER-POSED IMPELLERS: Features two counter-posed impellers that work together to multiply water pressure up to 40.8m while keeping a steady flow rate up to 80 L/min.
MAXIMUM ENERGY SAVINGS: Advanced twin-impeller design multiplies output pressure without requiring a massive, power-hungry motor, optimizing electrical draw (0.74 kW / 1 HP) to lower your power bills.
CONSTANT HIGH PRESSURE: Ideal for home pressure boosting (autoclave tanks), civil pressurization, and irrigation systems that need consistent, strong water flow across multiple open taps.
HEAVY-DUTY CAST IRON CONSTRUCTION: Built to handle daily continuous duty with a solid cast iron pump casing and motor bracket, AISI 416 stainless steel motor shaft, and ceramic-graphite-NBR mechanical seal.
VERSATILE & RELIABLE ITALIAN QUALITY: Handles water temperatures up to 50°C with Noryl® impellers. Includes built-in thermal protection on 230V models and IPX4 splash rating.
Product information
The Pentax CB 100 (single-phase) and CBT 100 (three-phase) are high-performance Italian two-impeller centrifugal electric water pumps designed for residential, civil, and industrial water pressure boosting. Built with a heavy-duty cast iron body and motor bracket, they offer outstanding structural strength and long-term durability for continuous daily operation.
The key feature of the CB 100 is its two counter-posed impellers. By mounting two impellers facing opposite directions on the same shaft, the pump doubles the output pressure without increasing the overall size of the pump. It delivers up to 40.8 meters of lift head and a flow rate of 80 L/min with a maximum operating pressure of 6 bar.
Engineered to optimize energy efficiency, the 0.74 kW (1 HP) motor delivers high hydraulic pressure with low electrical consumption. Available with Noryl® impellers (CB 100/00) or brass impellers (CB 100/01), it includes a stainless steel AISI 416 shaft end, ceramic-graphite seals, and built-in thermal motor protection on single-phase models. The Pentax CB 100 is the ultimate energy-saving, high-pressure choice for building automatic household water systems.
Note: Suitable for clean water and non-aggressive liquids at temperatures up to 50°C (Noryl®) or 90°C (brass). Protect from direct weather conditions during installation.
