ESPA ASPRI 20 5M centrifugal multistage surface pump

The ESPA ASPRI 20 5M electric pump is a high-efficiency multistage surface unit designed specifically for systems requiring stable pressure and high performance. It is ideal for autonomous household water supply, supporting domestic appliances, irrigation setups, and boosting pressure in centralized water networks.

Thanks to its horizontal multistage design, the pump delivers strong pressure, precise and stable flow, and the built-in self-priming valve allows water lifting from depths up to 9 meters, even when the suction line contains air. This makes the model one of the most user-friendly in its class.

Key Applications of ESPA ASPRI 20 5M

The pump is perfect for:

▪️ autonomous water supply for country houses, cottages, and private properties
▪️ boosting pressure in centralized water-supply systems
▪️ ensuring stable operation of household appliances (boilers, washing machines, dishwashers)
▪️ creating drip and automatic irrigation systems
▪️ supplying water to agricultural irrigation networks
▪️ filling tanks, reservoirs, and swimming pools
▪️ water-treatment, cooling, and air-conditioning systems

ASPRI 20 5M demonstrates high reliability and is suitable for both domestic and semi-professional operation.

High-Quality Materials

The pump is built using durable, moisture-resistant, and corrosion-proof materials:

▪️ Pump casing and impellers: AISI 304 stainless steel
▪️ Diffusers: impact-resistant technopolymer
▪️ Motor shaft: hardened AISI 420 stainless steel
▪️ Suction and discharge fittings: brass
▪️ Mechanical seal: graphite + aluminum — long-lasting and leak-proof
▪️ Motor housing: aluminium with efficient air cooling
▪️ Seals: EPDM and NBR — resistant to wear and temperature changes

This combination of materials increases service life and protects the pump from corrosion, water-hammer effects, and mechanical particles.

Operational Capabilities

▪️ Maximum water temperature: up to 40°C
▪️ Maximum suction height: 9 meters
▪️ Suitable for long-term continuous operation
▪️ Compatible with pressure tanks, pressure switches, and automation systems

The multistage centrifugal hydraulics deliver stable pressure, and the low noise level allows indoor installation or installation near living areas.
