Delavan Roller Pumps
are economical, moderate duty pumps covering a flow range of 6.5 gpm to 46
gpm. They are used for low volume, moderate pressures pumping
applications. |

|
Delavan Centrifugal Pumps are hydraulically
powered for high volume pumping applications. A common shaft
eliminates the need for external couplings or bearings. Viton pumps
seals are standard. Compact size allows a range of installation
points. Delavan Centrifugal Pumps use high quality Gresen motors.
Note: the hydraulic motor is designed to be non-reversible because the pump
will not deliver full capacity when running in reverse. |

Delavan Turbo-90 Pumps
are designed to operate directly from a 1000 rpm
PTO shaft without attachments. The Turbo-90 can pump suspended
materials without accumulation unlike a conventional turbine pump.
This is possible because of Pressure Relief Passages from the seal cavities
to the inlet port. The suspension circulates and, therefore is cleared
from the inner cavities. It can be used for large quantity liquid
transfer, from trucks to tanks for instance. It is also suitable for
high volume sprayer pumping applications. Note: A high
capacity strainer with a 20 mesh screen must be used on the inlet side.
A 1000 rpm PTO Coupler must also be used. The capacity or flow of the
Turbine 90 pump used with a 540 rpm PTO Coupler is about zero.
