Quantum pump is built to be quiet, durable and reliable. The motor materials are rustproof, with a stainless-steel motor shaft and sealed bearings that never need lubrication. The thermoplastic housing is built to withstand extreme heat and resist corrosion. Includes a pre-filter with a large strainer to prevent the entry of any foreign objects which could cause damage to the hydraulic parts of the pump, with a see-through lid for easy inspection. The hydraulic design moves water more efficiently and quieter than any other pump in its category.
