Zozhi HS112m1-4 5.5hp 4kw 3 Phase Hollow Shaft Electric Motor For Pressure Washer

Hollow shaft electric motors are designed to allow direct coupling with piston pumps. They are designed to work with the most common pumps on the market. They are available in different versions and powers

With the Hollow Shaft solution, the overall space of the motor-pump unit is reduced because the direct coupling allows the elimination of the elastic joint and the bell necessary for the coupling to the standard motors.

Direct motor-pump coupling is a simple, economical, and highly reliable solution. With our products are guaranteed mechanical machining of extreme precision. The precision of the “shaft-motor / shaft-pump” coupling allows the operation and safe use of the unit for long periods of time, without faults.

If you have some special needs or uses,please contact us.

Advantage:

1. Use high-quality magnetic materials to ensure sufficient output power, small working current, effectively reduces temperature rise, good heat dissipation, and high efficiency.

2. high-quality bearings and rigid assembly to achieve low noise operation.

3. tailor-made for professional equipment, shaft extension through high-frequency quenching treatment significantly improves mechanical strength, seamless connection with gear, and worry-free operation.

Protection

hollow shaft motor is IP-44 protection as defined in IS:4691 Motors can be supplied with IP-54 and IP-55 on request

Insulation

Hollow shaft motors supply with class B&F insulation as a standard feature.

Terminal Box

all three-phase motor supply with a terminal box on top for Foot mounted. Other position boxes like left or right supply on customer request.

Shaft

Hollow shaft motor shaft made from high carbon steel pipe to provide exceptional strength&rigidity to minimize deflection. we can also supply the motor with stainless steel hollow shaft

Rotor

All hollow shaft motor rotors are of high-pressure E.C. Grad aluminum die-cast. Every rotor is dynamically balanced. Thus, it makes low motor amplitudes of vibration & noise.
