Tuthill L Series Lubrication Pump

Tuthill L Series Lubrication Pump

L series pumps are precisely machined and assembled with only two moving parts, so they achieve and retain their reliability over a wider range of viscosities than alternative pump designs. They are also available with Tuthill’s unique reversing feature, as well as mounting, driving and sealing options to suit all your applications.
