The 50:1 ratio Panther® pump is suitable for grease distribution to multiple dispensing points or for dispensing distances of up to 300 feet. Because of its superior flow rate and rugged design, it is ideal for a wide variety of applications and installations. The Panther's proven air motor features a precision air reversing valve mechanism with dual valve ports for improved high speed breathing.
It also contains a positive trip detent spool mechanism that eliminates stalling (blowing air) by preventing the pump from being caught between strokes. The lower end is fitted with Balcrank's exclusive, patent-pending intake system that dramatically improves the pump's output by maintaining a high inlet vacuum. By creating such a high intake vacuum, the chance of producing "voids" in the grease is practically eliminated. It has a simple yet durable construction with all internal parts lubricated at the factory using a life tested synthetic grease (Balcrank P/N 826733). This grease coats all internal parts and repels air line moisture to inhibit corrosion.
The Panther® pump's exterior is constructed from aircraft grade extruded aluminum for an outstanding strength to weight ratio. The pump also has high quality Buna-N and urethane seals. It is a pump that has proven to be reliable, yet easy to service and maintain.
