Non Sine Palma Pulvere literally means "Not Without Dust On The Palm" however some may translate it as "No Palm Without Dust"
Pulvere is the ablative case of Pulvis, which means dust. In latin when the noun is of the dative or ablative case you may automatically add to/for for the dative case and in/out/with/.etc for the ablative case.
both translations basically mean you have to work hard (dust on the palm comes from working. get it?)
