English term (edited): let the pump stroke/to stroke slowly back and forth

mi traduccion:


una "Sand pump"bomba de arena: es una bomba de pistón.

Aqui "stroke"no es golpear sino que es el acto del pistón de bombear moviéndose hacia adelante y hacia atrás dentro de un cilindro, en una longitud determinada de ese cilindro desde el punto A hasta el punto B, a la que se le llama "stroke" o "carrera"del pistón .

Let the pump stroke= permita que la bomba (o el pistón) bombee.

The sand pump will now start to stroke slowly back and forth= El pistón de la bomba ahora comenzará a moverse (o bombear) lentamente hacia atrás y hacia adelante
