The Mayer GPD 15-12 A circulation pump is a modern pressure-boosting pump with a “wet” rotor, specially designed to ensure stable water pressure in apartment, house, and cottage water supply systems. The model provides consistent water delivery even under low or unstable pressure, ensuring maximum comfort when using household appliances, faucets, and shower systems.
Thanks to its optimized hydraulic design, the pump operates almost silently, making it suitable for installation inside living spaces without causing disturbance. High-quality materials and well-engineered mechanics guarantee long service life and high operational efficiency.
Operating Conditions
The pump is designed for pumping clean water or liquids similar in density and chemical composition.
Mechanical impurities of up to 0.01% are allowed, and the maximum particle size must not exceed 0.05 mm — ensuring long-lasting protection of internal components.
Design Features of Mayer GPD 15-12 A
The model is built in a horizontal monoblock design with a single closed centrifugal impeller, which increases efficiency and reduces hydraulic losses.
Key structural components:
▪️ Cast-iron pump chamber housing — corrosion and vibration resistance.
▪️ Closed-type centrifugal impeller made of polymer — excellent wear resistance.
▪️ Metal-ceramic shaft — enhanced durability and rotational stability.
▪️ Ceramic radial bearings — silent operation and minimal wear.
▪️ AISI 304 stainless-steel rotor sleeve — improved corrosion resistance.
▪️ AISI 304 deflector — protects electrical parts from moisture.
▪️ Aluminum motor housing — effective heat dissipation and low weight.
▪️ Built-in flow sensor — automatic start/stop depending on water flow.
▪️ Two operating modes: automatic and manual — flexibility in use.
▪️ Connection nuts included — easy installation without extra accessories.
Pump Motor
▪️ Asynchronous motor with a wet rotor — reliable and compact.
▪️ Enclosed construction protected against moisture.
▪️ Cooling is provided by the water being pumped.
▪️ Operation modes are set via a mechanical three-position switch.
▪️ Single-phase design with an external capacitor placed in the terminal box.
▪️ Supports continuous operation, ideal for systems with constant water consumption.
