Multistage centrifugal surface pump ESPA TECNOPLUS 15 4M

The automatic pumping station ESPA TECNOPLUS 15 4M is a modern, compact and energy-efficient solution for autonomous and stable water supply in private homes, cottages, commercial buildings and small farms. The model is based on a multistage surface pump and features the unique ESPA Speed Driver (ESD) automatic pressure-regulation system, which maintains perfectly stable pressure regardless of water consumption.

Design and Features

▪️ horizontal multistage centrifugal pump;
▪️ closed impellers;
▪️ mechanical shaft seal;
▪️ forced air cooling of the motor;
▪️ built-in frequency converter (speed controller);
▪️ integrated check valve;
▪️ pressure gauge, hydraulic shock absorber and power cable — fully ready for installation.

All hydraulic components are made from corrosion-resistant materials: stainless steel and durable engineering polymers.

Self-priming and Performance

TECNOPLUS 15 4M has excellent self-priming capabilities:

▪️ up to 2 m with an unfilled suction line;
▪️ up to 5 m with a primed suction pipe.

The pump housing must be filled with water before startup, after which the unit automatically releases air and switches to stable operation.

TECNOPLUS 15 4M is ideal for:

▪️ potable and domestic water supply;
▪️ household appliances (dishwashers, washing machines);
▪️ irrigation, automatic watering and sprinkler systems;
▪️ swimming pools and storage tanks;
▪️ washing systems;
▪️ small farms and private homesteads.

It is also used in municipal applications — pressure-boosting, filtration, HVAC systems and fountain water supply.

Key Advantages of ESPA TECNOPLUS 15 4M

▪️ integrated ESD automation maintains constant system pressure;
▪️ energy savings of 40–50% thanks to variable-speed operation;
▪️ protection against overheating, dry-run, closed valve operation;
▪️ automatic restart algorithm after emergency shutdown;
▪️ ultra-low noise level;
▪️ tolerant to voltage fluctuations — operates at 230V ± 50%;
▪️ no external controllers or sensors required;
▪️ easy installation, high reliability and long service life.

ESPA TECNOPLUS 15 4M is the perfect pumping station for homes where energy savings, automation, stable pressure and quiet operation are essential.
