Delavan Turbo 90 PTO Turbine Pump with Face Seal, 1-1/2" NPT, 100 PSI, 1000 RPM PTO (26556-11)

The Delavan Turbo 90 (26556-11) is the face seal version of Delavan's PTO-driven T-90 turbine pump, built for severe service such as abrasive liquids. It runs directly from a 1,000 RPM PTO, delivers high volume for spraying and transfer and provides enough bypass flow for maximum tank agitation.

Key Features

• The Turbo™ 90 is designed to operate directly from a 1,000 RPM PTO shaft without attachments.
• Face seals designed for severe service (such as abrasives). Hard, wear-resistant phenolic rings press against ceramic seats.
• Peak performance at slower rotation means longer life of the seals.
• 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 cleaned from the inner cavities.
• It can be used for large quantity liquid transfer, from truck to tanks, for instance. It is well suited to high volume sprayer pumping applications.
• The impeller is made of low moisture absorption, corrosion-resistant, engineering grade thermoplastic. It has been designed to increase pump life and smooth operation because of less rotation weight.
• Bearings are isolated by drain cavities.
• 1-1/2” inlet and outlet ports permit unrestricted high volume flow.
• Because of the high capacity of the T-90, sufficient bypass flow is available to maintain maximum agitation.
• Shaft is made of stainless steel and has a 15/16” diameter with 1/4” keyway.

Specifications

Frequently Asked Questions

What is the difference between face seal and lip seal?

The face seal version (26556-11) is designed for severe service such as abrasives, using hard phenolic rings against ceramic seats. The lip seal version (26556-4) suits general spraying and transfer.

What PTO speed does it need?

It runs directly on a 1,000 RPM PTO. Maximum recommended speed is 1,250 RPM.

Can it pump abrasive or suspended solids?

Yes. The face seals are built for abrasive service, and the Turbo 90 can pump suspended materials without accumulation.

What are the ports?

1-1/2" female NPT inlet and outlet.

What is the impeller made of?

Corrosion-resistant, low moisture absorption engineering grade thermoplastic.
