Page 4: The Pumping Principle
Charge. Tuthill 4000 Series pumps are required to develop 25” mercury vacuum at 0 psi on factory test. While these pumps will develop as high as 27” of vacuum, it is a sound engineering practice to avoid extreme vacuum whenever possible. Select a pipe size to reduce line friction loss to a minimum. -
Page 5: Proper Installation
Tuthill 4000 Series pumps are supplied with both ports on the same plane. Pumps with this type of porting arrangement should always be installed with the ports facing upward to insure proper priming. If it is necessary to install the pump with the ports pointing to either side, it is recommended that the top port be the suction port. -
Page 6: Relief Valve Protection
Relief Valve Protection All 4000 Series models are positive displacement pumps. As the pump rotates, liquid is positively delivered to the discharge side of the pump. If the discharge line is closed off, pressure will increase until the drive stalls and/or fails, the pump breaks or ruptures, or the piping bursts. -
Page 7: Strainer Protection
WARNING All Tuthill pumps contain residual 200 SSU lube oil from the factory test. Determine if this is compatible with the fluid you are pumping. If the fluid is incompatible, consult the factory. If the pump is to operate at elevated temperatures, it should be brought up to operating temperature gradually. -
