Product Description
The NEH is a high-slip three-phase induction motor built to NEMA standards for beam pumping units (pump jacks). NEMA Design D characteristics give high locked-rotor torque with low locked-rotor current, smoothing the cyclic load of the pumping unit. It is supplied to oil fields in North America, the Middle East and Eurasia.

How to Order
For a fast, accurate quotation please send: rated power (kW), voltage and frequency, number of poles or speed, Ex marking or hazardous zone, mounting type, quantity and destination port. For a replacement, a photo of the old motor nameplate is the quickest way to match it.
Frequently Asked Questions
Do your explosion-proof motors have ATEX and IECEx certificates?
Yes. Wolong Nanyang explosion-proof motors, both low-voltage and high-voltage, are available with ATEX and IECEx certificates for Europe and international projects, and GOST for the Russian market. Tell us which certificate you need when you ask for a quote.
Can this motor replace my existing motor?
Yes. For new projects we quote and select the model to your requirements. For a replacement, please send a nameplate photo or outline drawing of the old motor, and we will match the shaft height, mounting and installation dimensions.
Can you supply replacements for Schorch, Brook Crompton or Morley motors?
Yes. Schorch, Brook Crompton and Morley belong to the Wolong Electric Group, and we can supply Wolong motors built to replace them, matched to your mounting dimensions.
Can you ship to my country, and what is the lead time?
Yes. We ship worldwide on CIF terms, or you can use your own forwarder. The usual production time is about 3 months, depending on the model and quantity.
What information do you need for a quotation?
Rated power (kW), voltage and frequency, number of poles or speed, Ex marking or hazardous zone, mounting type (e.g. B3, B35, V1), quantity and destination port. A nameplate photo of the old motor helps if it is a replacement.
