VENZ VS550/4 Centrifugal Pump 380V 5.5HP 4 x 4 Inch Cast Iron Impeller

VENZ VS550/4 Centrifugal Pump 380V 5.5HP 4 x 4 Inch Cast Iron Impeller
The cast iron impeller model is a high-performance water pump designed for transferring large volumes of clean water in a short time. The 3-phase motor delivers more stable performance and greater energy efficiency compared to single-phase household models. The cast iron impeller provides superior strength, impact resistance, and abrasion resistance. The large pump casing with 4-inch inlet/outlet ports delivers a maximum flow rate of up to 1,300 liters/min, making it ideal for factories, large-scale agricultural farms, and public drainage work.

Features

High-power 5.5 HP (4.0 kW) motor, compatible with 380V / 50Hz (3-phase) industrial electrical systems

Impeller made of heavy-duty cast iron; its high mass increases centrifugal force to move massive volumes of water.

Pump casing made of extra-thick cast iron with a wide-profile design and 4-inch water ports to maximize flow rate and minimize friction.

Stainless steel motor shaft prevents shaft rusting and extends mechanical seal service life.

3-phase motor provides consistent torque, high efficiency, and superior continuous duty capability compared to single-phase models.

Equipped with a cooling fan and extra-large motor cooling fins, providing rapid heat dissipation even during extended continuous operation.

Premium mechanical seal provides excellent protection against water leaks into the motor.

IP44 protection rating protects against dust and water splashes from all directions

Class F insulation can withstand accumulated operating heat up to 155°C.

Heavy-duty construction with a wide mounting base to reduce vibration during heavy-duty operation.

Applications

Transferring massive volumes of water from natural sources, holding ponds, or canals to large-scale agricultural areas

High-speed clean water transfer in industrial plants or wastewater treatment systems

Water circulation in large shrimp or fish ponds requiring high-volume water turnover

Flood drainage or general clean water draining in low-lying areas or construction sites

Irrigation water delivery systems prioritizing maximum flow rate with low to moderate head
