CBT751 Dual Impeller Centrifugal Pump 250l/min 90.7m Civil Plant
HIGH-EFFICIENCY COUNTER-POSED IMPELLERS: Features two counter-posed impellers that work together to multiply water pressure up to 90.7m while keeping a steady flow rate up to 250 L/min.
MAXIMUM ENERGY SAVINGS: Advanced twin-impeller design multiplies output pressure without requiring a massive, power-hungry motor, optimizing electrical draw (5.5 kW / 7.5 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 industrial 400V power and IPX4 splash rating.
Product information
The Pentax CBT 751/00 stands out as a premium Italian twin-impeller centrifugal pump, specifically developed for high-demand residential, civil, and industrial water pressurization. Constructed with a heavy-duty cast iron casing and bracket, this pump is built to deliver unyielding structural integrity and long-lasting daily performance.
The key feature of the CBT 751/00 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 90.7 meters of lift head and a flow rate of 250 L/min with a maximum operating pressure of 11 bar.
Engineered to optimize energy efficiency, the 5.5 kW (7.5 HP) motor delivers high hydraulic pressure with low electrical consumption. Available with Noryl® impellers, it includes a stainless steel AISI 303 shaft end, ceramic-graphite seals, and reliable three-phase industrial power. The Pentax CBT 751/00 is the ultimate energy-saving, high-pressure choice for building automatic household water systems.
Note: Ideal for pumping clean water and non-aggressive fluids with a maximum temperature of 50°C (Noryl®). Always protect the unit from direct exposure to the elements during setup.
