A foam pump having a flexible member for engagement with a dispenser, the pump being part of a refill unit including a product reservoir. The flexible connecting member extends from an extreme end of the pump and is received by an actuating carriage that is movably connected to an actuating mechanism. The flexible connecting member permits insertion of the pump into a dispenser, and may act to dampen actuating forces to reduce foam shearing. The flexible connecting member may be provided in the form of a flared tip that is received through an oval opening in the product dispenser, and the pump may include a locking member to prevent unwanted actuation thereof during insertion of the refill unit into the dispenser.
